The question of Sunni Arab participation in Iraq’s political order that has plagued the transition since its inception is as acute and explosive as ever. Quickly marginalised by an ethno-sectarian apportionment that confined them to minority status in a system dominated by Shiites and Kurds, most community members first shunned the new dispensation then fought it. Having gradually turned from insurgency to tentative political involvement, their wager produced only nominal representation, while reinforcing feelings of injustice and discrimination. Today, with frustration at a boil, unprecedented Sunni-Shiite polarisation in the region and deadly car bombings surging across the country since the start of Ramadan in July, a revived sectarian civil war is a serious risk. To avoid it, the government should negotiate local ceasefires with Sunni officials, find ways to more fairly integrate Sunni Arabs in the political process and cooperate with local actors to build an effective security regime along the Syrian border.

The origins of the crisis run deep. Throughout his seven-year tenure, Prime Minister Nouri al-Maliki has implemented a divide-and-conquer strategy that has neutered any credible Sunni Arab leadership. The authorities also have taken steps that reinforce perceptions of a sectarian agenda. Prominent officials – predominantly Sunni – have been cast aside pursuant to the Justice and Accountability Law on the basis of alleged senior-level affiliation to the former Baath party. Federal security forces have disproportionately deployed in Baghdad’s Sunni neighbourhoods as well as Sunni-populated governorates (Anbar, Salah al-Din, Ninewa, Kirkuk and Diyala). Al-Iraqiya, the political movement to which Sunni Arabs most readily related, slowly came apart due to internal rivalries even as Maliki resorted to both legal and extrajudicial means to consolidate power.

This past year has proved particularly damaging. As events in Syria nurtured their hopes for a political comeback, Sunni Arabs launched an unprecedented, peaceful protest movement in late 2012 in response to the arrest of bodyguards of Rafea al-Issawi, a prominent Iraqiya member. It too failed to provide answers to accumulated grievances. Instead, the demonstrations and the repression to which they gave rise further exacerbated the sense of exclusion and persecution among Sunnis.

The government initially chose a lacklustre, technical response, forming committees to unilaterally address protesters’ demands, shunning direct negotiations and tightening security measures in Sunni-populated areas. Half-hearted, belated concessions exacerbated distrust and empowered more radical factions. After a four-month stalemate, the crisis escalated. On 23 April, government forces raided a protest camp in the city of Hawija, in Kirkuk province, killing over 50 and injuring 110. This sparked a wave of violence exceeding anything witnessed for five years. Attacks against security forces and, more ominously, civilians have revived fears of a return to all-out civil strife. The Islamic State of Iraq, al-Qaeda’s local expression, is resurgent. Shiite militias have responded against Sunnis. The government’s seeming intent to address a chiefly political issue – Sunni Arab representation in Baghdad – through tougher security measures has every chance of worsening the situation.

Belittled, demonised and increasingly subject to a central government crackdown, the popular movement is slowly mutating into an armed struggle. In this respect, the absence of a unified Sunni leadership – to which Baghdad’s policies contributed and which Maliki might have perceived as an asset – has turned out to be a serious liability. In a showdown that is acquiring increasing sectarian undertones, the movement’s proponents look westward to Syria as the arena in which the fight against the Iraqi government and its Shiite allies will play out and eastward toward Iran as the source of all their ills.

Under intensifying pressure from government forces and with dwindling faith in a political solution, many Sunni Arabs have concluded their only realistic option is a violent conflict increasingly framed in confessional terms. In turn, the government conveniently dismisses all opposition as a sectarian insurgency that warrants ever more stringent security measures. In the absence of a dramatic shift in approach, Iraq’s fragile polity risks breaking down, a victim of the combustible mix of its long­standing flaws and growing regional tensions.
