Iraq Marks Sovereignty Day as Final US Troops Depart, Ending Coalition Mission Against ISIL

Iraq staged military parades in two of its most symbolically significant cities on Wednesday to commemorate a newly established national holiday, Sovereignty Day, following the departure of the last remaining United States troops from the country. The celebrations in Baghdad and Najaf came as the final soldiers crossed out of Iraqi territory, formally drawing to a close the US-led coalition operation that had been mounted against the armed group ISIL.

The holiday, declared a national occasion by Iraqi authorities, is intended to memorialise the completion of the foreign military presence that began with the 2003 invasion and continued in various forms for more than two decades. Security forces took part in organised marches, with units displaying equipment and marching in formation as officials framed the moment as a restoration of full national control over security affairs.

Wednesday's withdrawal saw the remaining personnel leave the country, according to the account provided, ending a coalition mission that had operated with a mandate focused on combating ISIL. The coalition had been active in Iraq since 2014, when the group seized large swathes of northern and western territory, prompting a request from the Iraqi government for international assistance.

The fight against ISIL involved a combination of Iraqi ground forces, Kurdish Peshmerga units, and coalition air power, with the coalition providing surveillance, intelligence, and training support in addition to strikes. Major urban battles in Mosul, Ramadi, and Fallujah eventually reversed the group's territorial gains, though the campaign left significant destruction and a long reconstruction challenge.

The decision to wind down the coalition presence reflects a years-long negotiation between Washington and Baghdad over the shape and duration of the American military footprint. Iraqi political factions had repeatedly called for a timetable for departure, arguing that the continued presence complicated the country's claims to full sovereignty and provided recruitment arguments for armed groups opposed to the government.

Analysts note that the timing of the withdrawal carries domestic political weight. Successive Iraqi governments have sought to present the end of the foreign mission as a milestone in the country's recovery from decades of conflict, and the creation of a formal holiday allows that narrative to be institutionalised in the national calendar. The choice of Najaf as one of the parade locations is notable, given the city's status as a major centre of religious authority and pilgrimage.

At the same time, the departure raises questions about the capacity of Iraqi security forces to sustain counterterrorism pressure without coalition enablers. Iraqi commanders have expressed confidence in their units' readiness, citing improvements in intelligence gathering, air capability, and border control. Independent observers, however, caution that ISIL continues to operate as a dispersed insurgency, mounting hit-and-run attacks in rural and desert areas.

The coalition's drawdown is also likely to reshape regional dynamics. Neighbouring states have closely monitored the US presence in Iraq, viewing it variously as a stabilising factor or as a source of friction. A reduced American footprint may open space for renewed diplomatic and economic engagement by regional powers seeking influence in Baghdad, particularly in energy and infrastructure sectors.

For ordinary Iraqis, the significance of the day is likely to be mixed. Many will welcome the end of a foreign military presence that has been a polarising feature of national life, while others remain focused on chronic concerns such as unemployment, unreliable electricity, and weak public services. The parades offer a moment of official pageantry, but the underlying debates about governance and reconstruction are unlikely to be settled by a single ceremony.

The coalition mission had already undergone substantial transformation in recent years, shifting from a combat role to one centred on advising, training, and equipping Iraqi forces. Several partner countries had reduced their contributions ahead of the final withdrawal, leaving the United States as the principal remaining contributor. The closure of the mission therefore also marks the end of a multinational framework that once involved dozens of nations.

Officials framed Sovereignty Day as an assertion that Iraq alone now bears responsibility for its territorial defence. That framing places pressure on the government to demonstrate that its forces can prevent any resurgence of organised armed activity. Failure to do so would undercut the political message attached to the holiday and could revive calls for external assistance under different arrangements.

There is also a symbolic dimension tied to the country's broader reckoning with the post-2003 era. The invasion, the subsequent occupation, the sectarian violence of the mid-2000s, and the ISIL crisis are all bound up with the foreign military presence that is now formally concluding. Marking its end offers a way for the state to draw a line under a troubled period, even as the legacies of that period persist in damaged infrastructure and displaced communities.

Military parades in Baghdad and Najaf were accompanied by official statements celebrating the security forces, whose public standing has fluctuated over the years. The events were presented as a tribute to those who fought against ISIL and to the institutions that survived the country's most severe internal crises. Coverage of the occasion emphasised national unity and the completion of a process that many Iraqis had long demanded.

What follows the withdrawal will depend heavily on political and economic conditions. A stable security environment requires not only capable armed forces but also functioning local governance, dispute resolution, and economic opportunity in areas that were once held by ISIL. Development in those provinces has lagged, and humanitarian organisations continue to report needs among families who returned after displacement.

Wednesday's departure thus closes one chapter while raising the stakes for the next. Iraq has formally regained sole authority over its security landscape and has designated a day to remember the moment. Whether that authority translates into durable stability will be tested in the months ahead, as the country navigates internal tensions and a regional environment that remains unsettled.
