The final American military transport didn't just leave a tarmac in Erbil; it closed a chapter of Middle Eastern history that began more than two decades ago. When Baghdad declared a multi-day holiday known as Sovereignty Day, the streets filled with convoys flashing victory signs and crowds celebrating the complete departure of U.S. forces. Operation Inherent Resolve is officially over. The anti-Islamic State coalition mission that brought foreign troops back into the country in 2014 has wrapped up entirely.
If you're wondering what this actually means on the ground, the reality is far more complex than a simple military handoff. This isn't just about empty bases or shifting geopolitical chess pieces. It marks a total rewrite of how Iraq interacts with Washington, Tehran, and its own internal armed factions.
The Long Road to September 30
Let's be clear about the timeline because timelines matter. The U.S. military footprint didn't vanish overnight. The groundwork for this final exit was laid years prior, accelerating sharply through 2025 and 2026. Al-Asad Airbase transferred fully to Iraqi control early in the year, and by the time the last personnel packed up their gear from Erbil Air Base, the writing was on the wall.
Washington and Baghdad agreed on a planned transition. The U.S. Central Command confirmed that the orderly departure marked the conclusion of the anti-ISIS campaign as it had been structured since the Obama administration. But let's look past the diplomatic press releases. The truth is that mounting regional pressures, repeated militia strikes, and a changing political landscape in Baghdad forced an endgame that both sides knew was coming.
What Baghdad Celebrates and What It Ignores
To understand the celebrations on the streets of Baghdad, you have to look at the domestic narrative. Prime Minister Ali al-Zaidi's government has framed the exit as the ultimate assertion of national independence. For millions of Iraqis, foreign boots on the ground—regardless of their stated purpose—remained a painful reminder of the 2003 invasion and the decades of instability that followed.
Yet, local analysts point out a glaring irony that mainstream reports often gloss over. Iraq originally invited the U.S. coalition back in 2014 when ISIS swept across a third of the country and threatened the capital itself. Now, with the territorial caliphate crushed, the political winds have shifted toward asserting sovereignty by telling those exact same allies to pack their bags.
You also have to ask yourself: what happens to the internal security vacuum?
The Regional Power Vacuum and Iran's Next Move
The departure of American troops leaves a massive opening, and nature abhors a vacuum—especially in the Middle East. With Operation Inherent Resolve shifting its headquarters to Jordan to manage operations in Syria, Iraq stands entirely on its own two feet for domestic security.
This is where things get messy. Prime Minister al-Zaidi faces immense pressure regarding the disarmament of powerful Iran-backed militias. Implementation plans have already faced delays because domestic political factions view these groups as essential protectors. Critics argue that without American presence to check regional friction, domestic politics will tilt heavily toward Tehran's sphere of influence.
If you think the security situation is neatly resolved just because the foreign flags came down, you're missing the entire plot. The real test of Iraqi sovereignty isn't about who leaves the country; it's about whether Baghdad can control the armed groups operating inside its borders without plunging back into civil unrest.
Where the U.S.-Iraq Relationship Goes From Here
Diplomats are working overtime to spin this as a normal bilateral defense partnership. The narrative claims that moving from a combat and coalition mission to standard diplomatic and military-to-military ties is a sign of normal nation-building.
Maybe. But diplomacy rarely operates in a vacuum. The U.S. footprint is shrinking to a small diplomatic security contingent, and the regional posture of the West is permanently altered.
Watch the border regions closely over the next six months. Pay attention to how Baghdad handles security coordination with neighboring states and whether economic reforms can actually keep young Iraqis from seeking futures abroad. The party in the streets is over, and the hard work of governing a truly independent state has just begun.
