The last United States and United Kingdom troops have left Iraq, bringing an end to the coalition's anti-Islamic State mission in the country and marking a significant political and security turning point for Baghdad, Washington and London. The withdrawal, carried out under a deal agreed two years ago, fulfills a central demand of the Iraqi government and closes a chapter that began with the rise of ISIS and the international military response that followed.
Mission Ends Quietly
The departure of the final coalition personnel underscores how the war against ISIS has evolved from large-scale combat operations into a narrower security partnership. For Iraq, the end of the foreign troop presence is likely to be presented domestically as a restoration of sovereignty, especially after years of pressure from political factions that argued the coalition's continued presence had outlived its original purpose.
For the United States and Britain, the withdrawal reflects a strategic recalibration rather than a simple exit. Both governments have repeatedly said that their military role in Iraq had shifted from frontline operations to advising, training and supporting Iraqi forces. The end of the mission suggests that the coalition now believes Iraqi security institutions are capable of carrying the burden of counter-ISIS operations with reduced foreign involvement.
The timing is also politically sensitive. Iraq has spent years balancing its security dependence on Western support with domestic demands to limit foreign military influence. The removal of coalition troops is likely to be welcomed by some Iraqi political blocs, while others may worry that the departure could create space for ISIS remnants or other armed actors to exploit gaps in intelligence, logistics or air support.
Baghdad's Sovereignty Push
The withdrawal was not sudden. It was the product of a deal reached two years ago, after sustained Iraqi pressure for a timetable to end the coalition presence. That agreement became part of a broader negotiation over the future of foreign forces in Iraq, where the government has faced competing demands from Washington, regional powers and domestic constituencies.
At the heart of Baghdad's position has been a desire to assert greater control over national security policy. Iraqi leaders have argued that the country can no longer be treated as a permanent theater for foreign military operations, particularly after the territorial defeat of ISIS. The departure of the last British and American troops is therefore more than a military milestone; it is a symbolic assertion of state authority.
Yet the practical consequences remain uncertain. Iraq still faces persistent security challenges, including ISIS cells operating in remote areas, political instability, militia influence and the risk of renewed regional escalation. The end of the coalition mission does not eliminate cooperation with the West, but it does change the terms of that relationship. Future assistance is likely to be more limited, more diplomatic and more carefully framed to avoid the appearance of occupation.
Strategic Aftermath
The coalition's exit will be watched closely across the Middle East. It may be interpreted by allies and adversaries alike as evidence that the post-ISIS security architecture in Iraq is entering a new phase, one in which local forces must shoulder more responsibility. That shift could strengthen Baghdad's hand in domestic politics, but it also raises the stakes for the Iraqi military and intelligence services.
For Washington, the withdrawal comes amid broader debates over the scope of American military commitments abroad. Ending the Iraq mission allows the administration to point to progress in reducing direct combat deployments, even as the United States continues to maintain a network of security partnerships in the region. For London, the move similarly reflects a reduced expeditionary footprint and a desire to align military presence more closely with clear political objectives.
The end of the mission does not mean the end of the ISIS threat. The group's territorial defeat years ago removed its so-called caliphate, but its insurgent networks have endured. Iraq's ability to prevent a resurgence will depend on intelligence sharing, border control, political cohesion and the capacity of its own security forces. Without those, the withdrawal could be remembered not as the conclusion of a successful campaign, but as the beginning of a more uncertain security era.
Even so, the departure of the last coalition troops is a watershed moment. It signals that the international military response to ISIS in Iraq has reached its formal end, and that the next phase of the struggle will be shaped less by foreign combat power than by Iraq's own political and security choices.
