The Legacy of 9/11 and the “War on Terror”: A Special Series

Crisis Group experts contribute their views on how the 9/11 attacks and the subsequent “war on terror” shaped the conflicts and crises they work on.

In September 2021, we launched a special series of articles, reports, videos and podcasts by Crisis Group experts on the impact of al-Qaeda’s 9/11 attacks and the U.S.-led “war on terror”. These cover how Islamist militancy and the military operations aimed at defeating militant groups have both reverberated in Washington and shaped peace and security across different regions, especially in South Asia, the Middle East and Africa.

For more work on the aftermath of 9/11 please see our global issue page Jihad in Modern Conflict.

Our ongoing work on Afghanistan can be found here.

Online Event | The War on Terror: Twenty More Years?

As the debate over U.S. Presidential War Powers heated in Washington, we presented an online pannel discussion and Q&A, jointly organized with Just Security: "The War on Terror: Twenty More Years?". 

In an effort to assess 20 years of the United States's so-called War on Terror, the International Crisis Group recently released a report, Overkill: Reforming the Legal Basis for the U.S. War on Terror, which charts how the executive branch expanded the use of military force over the last two decades.

Online Event 22 October 2021. 

Online Event | How will the Taliban Victory Impact Other Conflicts Involving Jihadist Militants?

Could the seizure of Afghanistan by the Taliban just before the twentieth anniversary of al-Qaeda’s 9/11 attacks be a turning point for jihadist militancy worldwide? Two decades after those attacks, the U.S. administration withdrew its forces from Afghanistan and the Taliban quickly took control of the country. This followed direct talks between the U.S. and the Taliban and an agreement they reached in February 2020 for the U.S. to pull out troops from Afghanistan in exchange for – amongst other things – guarantees the Taliban would not allow transnational militants to use Afghan soil for plotting attacks abroad.

This online event explored the impact of the Taliban takeover on other wars involving al-Qaeda and ISIS-linked groups. Crisis Group analysts discussed the perceptions of jihadists and their enemies in the Sahel, Somalia and Syria of the dramatic events in Afghanistan and what they might mean for those conflicts in which they are fighting.

Commentary | Misunderstanding Yemen

U.S. efforts to uproot al-Qaeda’s Yemeni franchise often overlooked the country’s mercurial politics. As part of our series The Legacy of 9/11 and the “War on Terror”, Peter Salisbury explains that the sectarianism the group espoused is still rife on all sides of Yemen’s war.

Report | Overkill: Reforming the Legal Basis for the U.S. War on Terror

After the 9/11 attacks, the U.S. Congress passed a use of force authorisation that successive presidents have used to expand military action ever further. As part of our series The Legacy of 9/11 and the “War on Terror”, we argue that Washington should enact a new statute that promotes transparency and narrows the war’s scope.

As part of our series The Legacy of 9/11 and the “War on Terror”, Joost Hiltermann argues that the U.S. invasion of Iraq gave rise to a fierce variety of Sunni Islamist militancy, one just as intent on killing Shiite Muslims as on fighting the U.S. occupation.
