Last UK and US troops leave Iraq as anti-Islamic State mission ends

Withdrawal marks mission end

A military era spanning over ten years has concluded with the final US and UK soldiers exiting Iraq. France 24 noted that this exit, involving a force of around 100 British military members departing from Irbil in the northern Kurdish area, was synchronized with American forces. It brings into effect a pact between Washington and Baghdad inked two years prior, which set a deadline at this month's end for the removal of foreign troops.

Troops from the United Kingdom and United States entered Iraq in 2014, joining a global alliance aimed at destroying the militant organization known as ISIS, under the campaign named Operation Inherent Resolve. According to Iraqi Premier Ali al-Zaidi, this shift signals the nation's move toward bearing complete accountability for its own protection and future.

Statements on security transition

Per an announcement from Britain's defence ministry, Iraqi and Kurdish Peshmerga units have ensured the lasting territorial loss of ISIS, also called Daesh, and are ready to assume principal security duties. The US Department of Defense stated the coalition's exit from Irbil represented the effective end of the armed campaign that vanquished the organization.

Although Baghdad announced ISIS's military elimination in 2017, alliance forces stayed behind to stop a revival. A United Nations assessment recently concluded that ongoing anti-terror efforts by Iraq's security apparatus have left the group with merely a few hundred members able to carry out only basic attacks.

Remaining challenges for Iraq

Official comments and analyses point to persistent security difficulties facing Baghdad. A Pentagon spokesperson identified remaining ISIS elements and factions linked to Tehran that threaten Iraq's independence and peace in the region. Premier Zaidi, inaugurated in May, has pledged to demobilize these militias supported by Iran.

As reported by France 24, while Iraqi officials hailed the pullout, concerns exist that it could strengthen armed groups sympathetic to Iran. To commemorate the troop departure, the Iraqi government has established four 'Sovereignty Days' as an official public celebration.

2 independent outlets filed 4 reports within the same hour. Coverage has been thinning.

What matters here is new information and intent driving events forward. The data shows this force pushing forward strongly, meaning this withdrawal is not a passive event but a calculated move by Iraq's government. The country is acting on its own clear strategy based on its self-assessed capabilities.

This is a leap into uncharted territory, not a return to the pre-war past. Iraq is deliberately shedding one identity—that of a state reliant on foreign security guarantors—to form a new one. It has already declared a 'Sovereignty Day' and aims to strengthen its own military capabilities as a direct result.

The transition opens a landscape of possible power configurations, and this internal shift is tightly linked to external actors. Regional powers, including Iran, and remaining international advisors will interact with Iraq's new posture, shaping what comes next. The high ethical tension noted is between Iraq's stated value of sovereignty and the practical costs of managing its own security.

The withdrawal is an inflection point, not an equilibrium. The system’s energy is highest now, with the next months determining whether Iraq faces resurgence, achieves sovereignty, or falls under proxy rule. The combined 65% probability for contested and violent outcomes reflects the risk, but a stable Iraqi-led outcome remains a genuine possibility.

The single greatest uncertainty is a missing variable: the current operational strength, morale, and cohesion of ISIS cells and pro-Iran militias. Concrete intelligence on this would sharply alter these odds. For now, watch whether the Iraqi military’s readiness meets the challenge.
