Flashpoint / Global 4 December 2019 Al-Tanf, Syria Share Facebook Twitter Email Print Back To Map I. Why it Matters Located in Syria on the Iraqi border and within miles of the Jordanian border, the U.S. garrison at al-Tanf has, since 2016, served as a launching point for counter-ISIS operations and training for Syrian opposition factions fighting the jihadist group. Iranian and Iran-backed forces are deployed in close proximity to the al-Tanf desert outpost, which sits on the strategically significant Baghdad-Damascus highway. U.S. forces in al-Tanf established a 55-km de-confliction zone, beyond which lie an array of forces described as either “pro-regime” or “Iran-backed” that have set up checkpoints in the area. Several incidents in recent months underscore al-Tanf’s potential as a flashpoint between U.S. and Iranian and/or Iran-backed forces. II. Recent Developments 4 December 2019 Speaking alongside U.S. Secretary of State Mike Pompeo, Prime Minister Netanyahu remarked that “we have been fortunate that President Trump has led a consistent policy of pressure against Iran. Iran is increasing its aggression as we speak even today in the region. They’re trying to have staging grounds against us and the region from Iran itself, from Iraq, from Syria, from Lebanon, Gaza and Yemen, and we are actively engaged in countering that aggression”. Netanyahu further maintained that “Iran’s aggression is growing, but its empire is tottering. And I say let’s make it totter even further”. Secretary Pompeo, citing unrest in Iraq, Lebanon and Iran, stated that “some of these are people that are seeking freedom and a reasonable way to live, and they recognise the threat that is posed by the kleptocrats that are running the Islamic Republic of Iran”. View More 14 November 2019 Addressing a Global Coalition to Defeat ISIS Small Group Ministerial meeting, Secretary of State Mike Pompeo asserted that “we’re watching the space once occupied by this fraudulent caliphate [ie, ISIS] like a hawk. That’s why we’re maintaining our residual presence at Tanf, in southern Syria, and our capacity to conduct air operations. We’ve repositioned some our troops in north east Syria and in the broader region as well, to make sure that ISIS will never get a second wind and to prevent ISIS from recapturing the oil fields”. “We are continuing to pursue a diplomatic resolution of the Syrian conflict with UN Security Council Resolution 2254 as the guide so that stability can, one day, return to this war-torn land”, Pompeo added. The coalition also issued a joint communique. View More 13 November 2019 U.S. Secretary of Defense Mark Esper stated that “our mission [in Syria] is the enduring defeat of ISIS. We're going to have about 500 to 600-ish troops there, at the end of the day. We're still moving troops out of northeastern Syria”. In related remarks, a U.S. senior official, referring to oil fields around Deir al-Zour, noted that “the oil is – has been, for the last four years, managed by our partner, the civilian side of our partner operation, the SDC [Syrian Democratic Council]… And we have every expectation they will be continuing to do that without any interference from us”. “Our role”, he added, “is one of ensuring that they’re not bothered by anybody in continuing to do what they’ve been doing for the last four years”. View More 7 November 2019 A senior U.S. defence official indicated that “the military mission in Syria continues. It is the defeat of ISIS, like it has been since 2014, shoulder-to-shoulder with our SDF [Syrian Democratic Forces] partners”. He further clarified that “the securing of the oil fields is a subordinate task to that mission, and – and the purpose of that task is to deny ISIS the – the revenues from that oil infrastructure”. Another defence official asserted that “everyone in the region knows where American forces are. We're very clear with anyone in the region in working to deconflict where our forces are. If anyone – we work to ensure that – that no one approaches or has – shows hostile intent to our forces, and if they do, our commanders maintain the right of self-defence”. View More 7 November 2019 Syria and Russia jointly issued a statement asserting that “in southern Syria, the U.S. continues to hold the illegally occupied 55-km zone around Al-Tanf and prevent the dissolution of the Rukban refugee camp”. “We urge the entire international community to exert pressure on the U.S., which continues to violate the international law by its illegal presence in Syria, and to oblige them to withdraw completely troops from the sovereign Syrian Arab Republic”, the statement added. View More 1 November 2019 The U.S. State Department in its Country Reports on Terrorism 2018 assessed that “the [Syrian] regime continued to provide weapons and political support to Hizbollah and continued to allow Iran to rearm the terrorist organisation”. It further contended that “the Assad regime’s relationship with Hizbollah and Iran grew stronger in 2018 as the regime became more reliant on external actors to fight opponents and secure areas”. View More 30 October 2019 Iranian Foreign Minister Javad Zarif stated that “we will be in Syria as long as the Syrian government and people want”. He went on to say that “it seems that the U.S. is staying to protect the oil and at least President Trump is honest to say what the U.S. intends to do”. View More 28 October 2019 Reaffirming that “the United States will retain control of oil fields in northeast Syria”, U.S. Defence Secretary Mark Esper stressed that “we will respond with overwhelming military force against any group that threatens the safety of our forces there”. Responding to a question on whether this mission “include[s] denying access, preventing Russian or Syrian forces”, Secretary Esper went on to assert that “the short answer is yes, it presently does, because in that case we want to make sure that SDF does have access to the resources in order to guard the prisons, in order to arm their own troops, in order to assist us with the Defeat ISIS mission. So that's our mission, is to secure the oil fields”. Esper also reaffirmed that “we also were given the earlier directive to retain forces at the Al-Tanf garrison”. View More 25 October 2019 U.S. Secretary of Defence Mark Esper indicated that “the U.S. will maintain a reduced presence in Syria to deny ISIS access to oil revenue as we reposition for the next phase of the Defeat ISIS campaign”. Esper added that “ultimately, we always intended, as the president directed, to maintain a presence at the Al-Tanf garrison”. He also revealed that “we are now taking some action… to strengthen our position at Deir el-Zour, to ensure that we can deny ISIS access to the oil fields”, which “will include some mechanized forces”. Previously, via Twitter, President Trump had stated that “perhaps it is time for the Kurds to start heading to the oil region”. View More 26 September 2019 The U.S. Department of Treasury issued sanctions against “one entity, three individuals and five vessels participating in a sanctions evasion scheme to facilitate the delivery of jet fuel to Russian forces operating in Syria”. In related comments, Secretary of State Pompeo stated that “the U.S. has concluded that the Assad regime used chlorine as a chemical weapon on May 19th in an attack at Latakia province, Syria… the U.S. will not allow these attacks to go unchallenged, nor will we tolerate those who choose to conceal these atrocities”. View More 26 September 2019 Secretary of State Pompeo stated that “the U.S. supports UN efforts to end military violence in Syria. Ongoing violence - fuelled by Iran and Russia - is exacerbating Syria’s dire humanitarian situation and must cease for a political solution to take root”. View More 18 September 2019 Iran’s President Rouhani remarked that “it is strange that the enemies of the region have not yet understood the power of the regional nations’ resistance… instead of admitting that Lebanon’s Hizbollah has high capabilities and power both in scientific and military knowledge and bravery in the field, or that a part of brave young people of Iraq have liberated different cities across the country from the hands of terrorists, and instead of admitting to the growth and greatness of nations like Syria and Yemen, they are seeking to accuse others”. View More 16 September 2019 President Rouhani remarked that “there is only a political solution to the Syrian crisis, and this can only be achieved through constructive interaction and participation by all Syrian people”. He further argued that “U.S. troops must leave the area as soon as possible and that the Syrian government's control must expand in the east and north of the Euphrates, as in the rest of Syria”. View More 11 June 2019 The U.S. Treasury Department announced sanctions against "sixteen individuals and entities associated with an international network benefiting the Assad regime", including a pair of companies based in Lebanon that "facilitated shipments of Iranian-origin petroleum to Syria". View More 31 May 2019 Secretary Pompeo reaffirmed that “our efforts in Syria are aimed at a political resolution … UN Security Council Resolution 2254 is the guidepost”. Pompeo went on to refer to “the work that we’ve done with the Turks in Manbij, west of the Euphrates River, and we are attempting to set up a system… call it a buffer zone, call it what you will – that will reduce risk of terrorists attacking from Syria into Turkey and reduce risks that Turkey will come south and disrupt Kurdish activity inside of Syria”. View More 29 May 2019 The U.S.’ diplomatic spokesperson asserted that “our maximum pressure campaign on Iran is designed to deny the Iranian regime, the world’s foremost state sponsor of terrorism, the means to conduct its destructive foreign policy. Our campaign is working”. She elaborated that “the campaign is starving Iran’s proxies of the funds they rely on to operate on behalf of the regime”, citing examples including Hizbollah, Hamas, the Syrian government and Shiite militias in Iraq. She went on to affirm that “we will continue to apply maximum pressure on the Iranian regime to deny it the means to conduct its destructive foreign policy and compel the regime to negotiate a comprehensive new deal that addresses the full scope of its malign behaviour”, while also indicating that “there is a path forward and we will talk tomorrow if they would like to see the bright future that we believe is there for the Iranian people”. The spokesperson further indicated that “we do not want a war with Iran. We want to de-escalate with Iran. In fact, what we seek is to end economic sanctions, to end the maximum pressure campaign”. View More 22 May 2019 The U.S. special representative for Syria, James Jeffrey, told the House Foreign Affairs Committee that “the [Trump] administration is pursuing three mutually reinforcing whole-of-government strategic objectives in Syria – the enduring defeat of ISIS, the removal of all Iranian-led forces from Syria and the resolution of the Syrian crisis through a political solution in line with UN Security Council Resolution 2254”. “The Iranian regime’s malign activity has left us no choice but to pursue the withdrawal of all Iranian-commanded forces from the entirety of Syria”, Jeffrey elaborated. “Iran’s reckless behaviour makes the situation in Syria more dangerous… Iranian-backed forces use bases inside Syria to participate in violence again[st] the Syrian people and launch attacks against Israel”. He added that “Iran and its proxies threaten U.S. national security by sowing instability in the region that exacerbates tensions between communities and provides space for terrorist groups to thrive”. View More 14 May 2019 U.S. Central Command indicated that remarks by a senior military official in the U.S.-led counter-ISIS campaign, who had stated that "there's been no increased threat from Iranian-backed forces in Iraq and Syria", "ran counter to the identified credible threats". CENTCOM's statement added that "OIR [Operation Inherent Resolve] is now at a high level of alert as we continue to closely monitor credible and possibly imminent threats to U.S. forces in Iraq". View More 27 April 2019 A senior U.S. military official asserted that "we're going to continue to reach out to our partners and friends in the region to ensure that we make common cause against the threat of Iran... I believe we'll have the resources necessary to deter Iran from taking actions that will be dangerous". He went on to indicate that "over the long term, we're going to reduce our forces in Syria, we recognise that, that's the guidance in which we're operating... that will be something that we will look at very carefully as we go forward". The U.S., he added, would maintain "a long-term presence in Iraq, focussed on the counter-terror mission". View More 16 April 2019 Foreign Minister Javad Zarif traveled to Damascus for meetings with President Assad and other senior Syrian officials. View More 4 April 2019 A senior Syrian official asserted that "Syria will liberate the occupied Golan by all means and all choices are on the table". He also argued that "the U.S. administration lies with regard to pulling out its troops, which are illegitimately deployed in Syria, and it isn't our duty to teach them to be honest". View More 25 March 2019 The U.S. added "dozens of new vessels involved in illicit oil shipments" from Iran to Syria in an update to a November 2018 advisory. A senior Treasury Department official noted that "the U.S. has made it clear to the maritime shipping community that we will not tolerate the use of petroleum as a mechanism to finance rogue regimes in Iran and Syria", adding that "as Iran and Syria attempt to adapt their illicit tactics and shift to new vessels, we will continue to provide these updates to the shipping community". View More 22 March 2019 The U.S. special representative for Iran, Brian Hook, noted that "we know historically that Iran has given Hizbollah an average of $700 million a year... we have seen evidence of the impact [of U.S. sanctions] when the leader of Hizbollah makes a public appeal for charity. It speaks for itself. This is the kind of impact that we want". He added that "we know that we have denied the [Iranian] regime even in the short amount of time [since sanctions came into effect] many billions of dollars in revenue", and underscored that the U.S. held "talks with any government where we see sanctions violations or even potential sanctions violations". Hook went on to underscore that "we are... committed to ensuring that troops under Iranian command are out of Syria", and suggested Iran had a "vastly-under reported role in Yemen" despite having "no legitimate interest" in the country. "Giving [Iran] a foothold in Yemen", Hook argued, "allows them to threaten two straits of international commerce". View More 20 March 2019 President Trump indicated that "in Syria we're leaving 200 people there and 200 people in another place in Syria, closer to Israel, for a period of time". He also predicted that remaining ISIS-held territory "will be gone by tonight". View More 18 March 2019 Iran's military chief of staff met with his opposite numbers from Syria and Iraq, pledging that "measures taken by the three countries will continue until terrorists are fully defeated". He also met with the Syrian president, Bashar al-Assad, in Damascus. View More 17 March 2019 During a trip to Syria, Iran's military chief of staff argued that "all foreign troops who are present in Syria without coordinating with the Syrian government will have to leave the country sooner or later". View More 7 March 2019 CENTCOM commander Joseph Votel posited that "the U.S. withdrawal from Syria represents the most dynamic shift in the environment since ISIS lost its ability to govern major population centres and fight as a conventional force and could trigger a renewed race for influence, control, and for some, survival". He further stated that "Israel's legitimate concerns about Iran's increasingly provocative actions in Syria, particularly the transshipment of advanced weapons systems into and through Syria, are driving increasingly forward-leaning Israeli military actions". View More 5 March 2019 President Trump replied to a 22 February letter from members of Congress calling for "a small American stabilising force in Syria" by bracketing a paragraph about ensuring "that ISIS never returns, that Iran is not emboldened" and noting "I agree 100 per cent - all is being done". View More 2 March 2019 President Trump assessed that "as of probably today or tomorrow, we will actually have 100 per cent of the [ISIS] caliphate in Syria... And we'll leave a small group of guys and gals. But we want to bring our people back home". View More 27 February 2019 Qods force commander Soleimani described Syrian President Bashar al-Assad's 25 February trip to Tehran as a "celebration of victory", adding that "you saw how Assad hugged the [Supreme] Leader with love, like a son who has been departed from his father. This is not a minor thing". Soleimani also assessed that "the most secure borders of our country is the common border with Iraq, and our friends are ruling the country". View More 26 February 2019 President Rouhani maintained that "we have achieved good victories in the political and international stages, and we have done great things in the region, parts of which were on the shoulders of the IRGC, the foreign ministry and the economic sectors". He added that the 25 February visit of President Bashar al-Assad "indicates that if we stand by each other, we will be successful". View More 25 February 2019 Syrian President Bashar al-Assad traveled to Tehran for meetings with senior Iranian officials. Supreme Leader Ali Khamenei asserted that "Syria... managed to stand strong against a big coalition of the U.S., Europe and their allies in the region and victoriously come out of it". He also warned that "the question of a buffer zone in Syria that the Americans are trying to create is one of their dangerous plots that must be firmly rejected and opposed". "Iran and Syria", Khamenei added, "are strategic allies and the identity and power of Resistance depends on their continuous and strategic alliance, because of which the enemies will not be able to put their plans into action". President Rouhani pledged that "Iran will stand by the Syria government and people like before". View More 23 February 2019 Iran's Supreme National Security Council Secretary, Ali Shamkhani, maintained that "we will stay in Syria and fight against terrorism as long as the legitimate Syrian government would make such requests". Addressing Israel's airstrikes, Shamkhani posited that "Israel is clearly taking steps to serve the interests of terrorists and to counter the Syrian government and army". "We severely responded to the [Israeli] attack on T4 and dealt a heavy blow to them", Shamkhani remarked. "We have made arrangements to protect our red line in the area of human casualties caused by any act of aggression and invasion". He also predicted that "we will soon witness a major upheaval in upgrading the deterrent power of resistance in Syria. I believe that the Zionist regime's officials, particularly their military and intelligence officials, are well aware of this issue. The method for tackling their Zionist regime's attacks on Syria and the axis of resistance in 2019 will be significantly different from the combat methods in the past". "We have accomplished more than 90 per cent of our objectives [in Syria]", Shamkhani maintained. "Thus, the Israeli punitive strikes have had no strategic impact and the resistance has pressed ahead with its activities". View More 22 February 2019 A U.S. official indicated that that approximately 200 U.S. troops would remain deployed at the al-Tanf garrison even as the U.S. proceeded to significantly reduce its military presence across Syria. View More 21 February 2019 The White House announced that following the withdrawal of U.S. forces, "a small peacekeeping group of about 200 will remain in Syria for a period of time". However, the following day media reports clarified that the figure may actually be 400. View More 14 February 2019 President Rouhani met with his Turkish and Russian counterparts for discussions on Syria. In a press conference, he suggested that "if the U.S. retreats its forces from Syria, based on our intelligence we know that they will continue to meddle in Syria". Rouhani also posited that "illegal interference in Syria by the Zionist regime [i.e. Israel] is a source of concern for the people of this country and other nations in the region. [The] Israelis bomb anywhere in the region and fly on Lebanese and Syrian soil whenever they wish, and unfortunately, the UN and global authorities are silent about these continued acts of aggression in Syria". View More 13 February 2019 Secretary Pompeo, in Warsaw for the Ministerial to Promote a Future of Peace and Security in the Middle East, described the proceedings as "absolutely historic... the first time in a quarter of a century that you had the prime minister of Israel in the same room talking about threats in the Middle East with senior Arab leaders from all across the Middle East". "This gathering is certainly about Middle East peace and stability," he explained. "You can't talk about that without talking about the threat from the Islamic Republic of Iran, whether it's Hizbollah, Hamas, the Houthis - I call them the three H's - whether it's their work against the Iraqi government... whether it's what they're doing in Syria today". Pompeo also remarked that "we don't expect the Iranian people to support the U.S. We expect them to take care of their own country... we want the Iranian people to have the opportunity to live in a prosperous, peaceful society and one that is controlled by their desires, their wishes. And if we can get that, I am very confident that these behaviours that we see in Iran will change dramatically". On Yemen, Pompeo stressed that "we have two problems - three problems really. The first problem is al-Qaeda... the second problem is Iran continuing to fund the Huthis... it provides missiles to the Huthis that they launch into airports in Saudi Arabia and the Emirates". View More 6 February 2019 In remarks to a ministerial meeting of the counter-ISIS coalition, President Trump indicated that "the U.S. military, our Coalition partners and the Syrian Democratic Forces have liberated virtually all of the territory previously held by ISIS in Syria and Iraq. It should be formally announced sometime probably next week that we will have 100 per cent of the caliphate". He went on to state that "as countries in the region and across our Coalition step up their commitments, as we continue to destroy the remnants - that's all they have, remnants. But remnants can be very dangerous". View More 6 February 2019 In remarks to a ministerial meeting of the counter-ISIS coalition, Secretary Pompeo maintained that "the drawdown of [U.S.] troops [from Syria] is essentially a tactical change - it is not a change in the mission. It does not change the structure, design or authorities on which the campaign has been based". Pompeo added that "in addition to this coalition's laser-like focus on defeating ISIS, we're committed to the following series of things. First, a political solution in line with UN Security Council Resolution 2254. The removal of all Iranian-led forces from Syria". View More 4 February 2019 Ahead of a ministerial meeting of the counter-ISIS coalition, a senior U.S. official noted that "we're entering a very critical phase in which we need to expand the diplomatic cooperation to assist the populations in Iraq and north-eastern Syria recover from ISIS' rule but also maintaining significant pressure on ISIS as it increasingly turns to insurgent tactics to destabilise both north-eastern Syria and Iraq". Another official further indicated that "our three top priorities [in Syria]... continue to be to secure an enduring defeat of ISIS, to see the exit of all Iranian-commanded forces from the entirety of Syria and to reach a political settlement of the conflicts under UN Security Council Resolution 2254". A third diplomat asserted that "we can't turn a blind eye towards the malign activities of Iran throughout the region", adding that "we expect Iran to fully respect the sovereignty of Iraq and other regional states, to cease their destabilising activities and to refrain from actions that enflame sectarian tensions". View More 16 January 2019 The IRGC's commander warned Israel to "fear the day when Iranian precision missiles hit you and take revenge of all the blood of oppressed Muslims which you have shed". "Iran will keep in Syria all the military and revolutionary advisors, and equipment and weapons which aim to train and empower Islamic resistance forces and support oppressed people of the country", he pledged, adding that "we do not take into account your ridiculous threats. You know that if we have chosen to wait against your hostile measures, some considerations lie behind it". In related comments, Iran's diplomatic spokesperson advised Prime Minister Netanyahu to "know your limits". View More 14 January 2019 A senior Iranian military official indicated that "as far as terrorists are in Syria and the country asks help from Tehran, Iran will continue its advisory presence in Syria". View More 13 January 2019 Via Twitter, President Trump indicated the U.S. was "starting the long overdue pullout from Syria while hitting the little remaining ISIS territorial caliphate hard, and from many directions. [We] will attack again from existing nearby base if it reforms. Will devastate Turkey economically if they hit Kurds. Create 20-mile safe zone..." He went on to add that "[we] do not want the Kurds to provoke Turkey. Russia, Iran and Syria have been the biggest beneficiaries of the long-term U.S. policy of destroying ISIS in Syria - natural enemies". View More 13 January 2019 Secretary Pompeo affirmed that "the roughly 2,000 uniformed soldiers that are in Syria today are going to be withdrawn. That activity is underway. We’re going to do so in an orderly, deliberate way, a way that protects America’s national security, a way that allows us to continue the important mission that they were on. The counter-terrorism mission, the effort to make sure that the destruction of ISIS is not only complete but that their resurgence is not possible, our efforts to counter the threat from terrorism stemming from the Islamic Republic of Iran – those are all real missions. The tactical change we’ve made in the withdrawal of those 2,000 troops is just that, a tactical change. The mission remains the same". View More 12 January 2019 Secretary Pompeo acknowledged that the U.S. goal of removing "every Iranian boot on the ground [in Syria] is an ambitious objective... but it's ours. It is our mission". Withdrawing U.S. forces from Syria, Pompeo explained, "is a tactical change. It doesn't materially alter our capacity to continue to perform the military actions that we need to perform. But even more broadly than that, the campaign to create a better world, to allow the Iranian people to have opportunity and democracy, has lots of pieces to it - economic, financial, diplomatic for sure". He went on to suggest that "the nuclear proliferation risks from Iran are incredibly real... our mission set is certainly to stop the terror regime, to stop the fighting of Hizbollah and Shiite militias and the Huthis... but it has a nuclear component". View More 10 January 2019 Secretary Pompeo pledged that "in Syria, the U.S. will use diplomacy and work with our partners to expel every last Iranian boot". "There will be no U.S. reconstruction assistance for areas of Syria held by Assad", he added, "until Iran and its proxy forces withdraw and until we see irreversible progress towards a political resolution".

View More 4 January 2019 A senior U.S. diplomat explained that "concerning Syria, we have no timeline for our military forces to withdraw... the President has made the decision that we will withdraw our military forces from Syria, but that it will be done in a deliberate, heavily coordinated way with our allies and partners". The diplomat went on to assert that "our military posture in Syria may be changing, but our overall goals in Syria remain the same, and key among those is... to see the withdrawal from Syria of all Iranian-commanded forces". View More 3 January 2019 Secretary Pompeo remarked that "the President is not ambiguous with respect to Syria. Our troops are coming out. The President also made very clear that we needed to continue the counter-ISIS campaign, and we needed to continue to ensure that we did the things to create stability throughout the Middle East. The counter-Iran campaign continues. We'll do all of those things......we will simply do it at a time when the American forces have departed Syria". Pompeo also discussed U.S. sanctions against Iran, stating that while "a well-supplied crude oil market" was a consideration for issuing sanctions waivers, "we want to ensure that we're complying with the requirements that the sanctions on Iran have the ultimate goal which we're trying to achieve: creating an outcome where the Iranian people... can have better lives than they have today under this tyrannical regime". View More 2 January 2019 President Trump asserted that "Iran is no longer the same country. Iran is pulling people out of Syria. They can do what they want there, frankly. But they're pulling people out. They're pulling people out of Yemen". "When we do all of the things that we've done monetarily to Iran", he added, "Iran is in trouble. And you know what? I'd love to negotiate with Iran. They're not ready yet, I don't think. But they will be. But Iran is a much different country right now... than it was when I took over". Asked about a timetable for pulling U.S. forces out of Syria, Trump responded that it would occur "over a period of time. I never said I'm getting out tomorrow. I said we're pulling our soldiers out, and they will be pulled back in Syria, and we're getting out of Syria... but we're getting out very powerfully".

View More 22 December 2018 Reacting to President Trump's decision to withdraw U.S. forces from Syria, Iran's Foreign Ministry opined that "in principle, the deployment and presence of U.S. forces in the region from the outset was a wrong, irrational and provocative move that created tensions". A senior Iranian military official also weighed in saying that "the Americans have come to the conclusion that they can exercise power neither in Iraq and Syria nor in the entire region". View More 20 December 2018 Explaining the U.S. decision to withdraw from Syria, Secretary Pompeo stressed that "the primary mission was to go take down the ISIS caliphate. That is at the very tail end of completion. And we have ISIS remnants in lots of pockets around the world". He added that the U.S. "intends to continue that counter-terrorism campaign, continue the fight against ISIS, whether it stems from Syria or other places". View More 20 December 2018 Elaborating on his decision to withdraw U.S. forces from Syria, President Trump asserted that "getting out of Syria was no surprise... Russia, Iran, Syria and others are the local enemy of ISIS. We were doing there [sic] work. Time to come home and rebuild". He went on to state that "Russia, Iran, Syria and many others are not happy about the U.S. leaving... because now they will have to fight ISIS and others, who they hate, without us." View More 19 December 2018 Prime Minister Netanyahu revealed that in conversations with President Trump and Secretary Pompeo, "the American administration told me that it is the president's intention to withdraw their forces from Syria. They made it clear that they have other ways of expressing their influence in the area". Netanyahu went on to say that "this is, of course, an American decision. We will study its timetable, how it will be implemented, and - of course - its implications for us. In any case we will take care to maintain the security of Israel and to defend ourselves in this area". View More 19 December 2018 President Trump announced that "we have defeated ISIS in Syria, my only reason for being there during the Trump presidency", while a White House statement indicated that "we have started returning U.S. troops home as we transition to the next phase of this campaign". View More 11 December 2018 A senior Russian defence official maintained that the U.S. was "holding with incomprehensible stubbornness the occupied 55-km area around al-Tanf where 6,000 armed militants are on the loose and are preventing the disbanding of the Rukban refugee camp". In related comments, a Russian diplomatic spokesperson suggested that "there is growing concern related to the dubious activity of the U.S. and its allies in Syria.

And there, according to numerous witness accounts, militant training is underway". View More 14 November 2018 The U.S. special representative for Syria, James Jeffrey, laid out U.S. objectives in Syria as "the enduring defeat of ISIS, a re-invigorated and irreversible political process... and de-escalation of the conflict that will include all Iranian-commanded forces departing from the entirety of Syria". Jeffrey elaborated that "on getting Iran out, that is basically part of a process. It's not a military goal of the U.S., it's not a mission of U.S. military forces... you will not have a lasting peace in Syria if Iran is doing the kind of power projection policies out of Syria that it has done through Hizbollah in southern Lebanon and done through the Huthis in northern Yemen".

View More 27 September 2018 The U.S. special representative for Syria, James Jeffrey, assessed that Iran's involvement in Syria reflects "capabilities that we would associate with power projection over the region. Very similar to what we've seen in southern Lebanon, very similar to what we have seen in northern Yemen". He went on to suggest that "a military presence long term, including power projection - which the Iranian seem to be aiming for - is a little bit more than their minimum goals and seems to be frosting on the cake. What we're trying to suggest is let's put pressure on them to leave". "We're not going to force the Iranians out of Syria", Jeffrey added. "This is all about political pressure".

View More See more III. Background As ISIS’s territorial control in Syria and Iraq shrinks, territories previously held by the group leave a vacuum for conquering parties to further their own influence and agendas. This includes both the U.S., which has been leading a counter-ISIS campaign under the framework of Operation Inherent Resolve, and Iran, which has deployed its own forces and backed non-Iranian militias against ISIS and anti-Assad forces in Syria. The capture and execution by ISIS of an Iranian Revolutionary Guard near al-Tanf in August 2017 confirms an Iranian presence on the ground there, though its extent is difficult to ascertain. Crowds gather in Isfahan for funeral of an IRGC Soldier killed by ISIS in Syria, 28 September 2017 TASNIM The view from Washington is that Iran’s strategic goal is to establish an east-west land corridor stretching from Iran to Lebanon as a back-up to the existing air corridor that serves as an Iranian arms supply channel to Hizbollah; control of al-Tanf would facilitate this objective. The view from Tehran is that the U.S. is seeking to develop a north-south corridor in eastern Syria, stretching from the Turkish to the Jordanian border and controlled by Syrian Kurdish parties and other U.S.-backed forces, to curtail Iran’s access to its allies and proxies in the Levant. IV. Analysis Limited Response to Douma. On the evening of 7 April 2018, the rebel-held Damascus suburb of Douma was subjected to an apparent chemical weapons attack. Retaliatory military strikes by the U.S. and its Western allies grew increasingly likely after Russia and the P3 - the U.S., the United Kingdom, and France - failed to agree on a mechanism at the Security Council, and were launched against targets in Damascus and Homs in the early hours of 14 April (Syrian time). President Trump declared that "the purpose of our action... is to establish a strong deterrent against the production, spread and use of chemical weapons", while the secretary of defence, Jim Mattis, described the operation as "a one-time shot". By keeping the strikes limited in duration and narrow in purpose, the U.S. and its allies likely wanted to avoid an unintended escalation; Russian officials confirmed that their air defences in Syria were not engaged during the operation. However, President Trump left open the possibility of future action, stating that "the combined American, British and French response to these atrocities will integrate all instruments of our national power: military, economic and diplomatic. We are prepared to sustain this response until the Syrian regime stops its use of prohibited chemical agents".
