The final American boots have left Iraqi ground. Two decades after a shock-and-awe invasion upended the Middle East, the US military footprint in Iraq has officially hit zero, concluding an agreement struck under the Biden administration to wind down operations by late 2026.
About 1,500 remaining personnel and anti-Islamic State coalition members packed up their gear and departed Baghdad, shifting their regional observation posts across the border into Jordan. The Pentagon insists its over-the-horizon capability remains sharp, ready to strike if militant threats resurface. But nobody in Washington or Baghdad is pretending this is just a routine redeployment. It marks the definitive end of an era defined by trillions of dollars, thousands of fallen service members, and hundreds of thousands of civilian casualties documented by projects like Brown University's Costs of War.

So what happens now? The vacuum left behind isn't empty. It's being claimed by the forces best positioned to fill it.
The Winners and Losers of the Exit
Iran is celebrating. For Tehran, the departure of American forces removes the primary thorn in its side right next door. Iranian officials wasted no time pointing to the withdrawal as proof that their resistance front outlasted superpower patience. For further context on this development, in-depth analysis is available on TIME.
Yet reality on the ground is messier than a simple victory lap. Decades of turmoil have left Iraq tethered to Iranian influence, seeded through political allies and powerful militias like the Popular Mobilisation Forces. These groups, numbering over 200,000 fighters, were originally organized to crush the Islamic State. Today, they operate as heavily armed factions with deep ties to the Islamic Revolutionary Guard Corps.
Baghdad faces an immediate test. The Iraqi government promised to disarm these militias, setting deadlines that stretch into mid-2027. But enforcement is already slipping. Reports from Iraqi officials suggest that major groups are spinning off splinter cells, handing over only fractions of their arsenals, and maintaining covert links with regional networks spanning from Yemen to Saudi energy infrastructure. When security falls entirely on local shoulders, prime ministers find themselves negotiating with armed actors who hold more guns than the state police.
The Regional Realignment
While Tehran feels emboldened, its aggressive posture over recent years has accidentally triggered a defensive wall across the Middle East. Strategic analysts point out an unexpected byproduct of the long conflict: quiet, pragmatic partnerships between Arab states and Israel. Facing shared threats from Iranian proxies, countries that once refused to sit at the same table have drawn closer, creating a geopolitical counterweight that would have seemed impossible back in 2003.
Washington's pivot to Jordan doesn't mean total disengagement. The Pentagon's new posture relies on remote surveillance and rapid-strike capabilities. If remnants of the Islamic State attempt to regroup and control territory the way they did a decade ago, US aircraft based in Jordan can and will intervene. But day-to-day containment of proxy warfare is no longer an American burden. It's an Iraqi crisis.
What Comes Next for Baghdad
Iraq sits at a dangerous crossroads. Its economy has shown signs of resilience, and its democratic institutions have survived incredible stress. But true sovereignty requires a state monopoly on violence. As long as splinter militias outgun the national army and take orders from foreign capitals, true independence remains out of reach.
The Americans are gone. The hard work of building a nation that answers only to its own citizens begins now.
