**Deck**: Baghdad’s national security chief says all remaining U.S. troops and air defenses will leave Iraq’s Kurdistan Region by September 30, reshaping the security map along Iran’s western border. The pullout leaves Kurdish authorities balancing between Tehran, Baghdad, and Washington just as regional threats are rising.

The planned withdrawal of all remaining U.S. troops and air defense systems from Iraq’s Kurdistan Region by the end of September will leave one of the Middle East’s most volatile frontiers without its long‑standing American security umbrella.

Iraq’s national security adviser said on 6 September that U.S. forces and anti‑air capabilities will depart the autonomous Kurdish region by 30 September, marking the end of a two‑decade American military presence that has underpinned Kurdish self‑rule and deterred cross‑border attacks. Washington has not publicly detailed the scope of the withdrawal, but the adviser’s statement signals that the remaining advisory and defensive footprint in the north is set to go.

For Kurdish civilians and local authorities, the shift is more than symbolic. U.S. radar and air defense assets have formed part of the shield against rocket, missile, and drone strikes by Iran and Iran‑aligned militias, which have repeatedly targeted Kurdish territory in recent years. Without that layer, residents and local security forces face a more direct exposure to regional power struggles that often play out via long‑range weapons rather than conventional ground assaults.

The decision also forces Kurdish security forces, long trained and supported by the United States, to consider how much they can rely on the Iraqi central government for protection. Baghdad has been trying to assert greater control over all foreign deployments, arguing that the Islamic State group has been degraded and that foreign troops are no longer needed in a combat role. Yet Iran‑backed militias retain influence inside Iraq’s formal security structures, shaping how and when the state responds to attacks on Kurdish soil.

Strategically, the U.S. pullback from Iraqi Kurdistan reduces Washington’s on‑the‑ground visibility and leverage along Iran’s western flank, at a time when Israel and Iran are trading sharper threats and Gulf states are recalibrating their security ties. American forces in the Kurdish north have provided not just protection against militants, but also a forward observation post in a region where missile ranges and drone swarms increasingly define military balance.

For neighboring Turkey, which conducts its own military operations against Kurdish militants in northern Iraq, the withdrawal could complicate deconfliction arrangements that have helped avoid incidents with U.S. forces. For Iran and armed groups aligned with it, the departure of U.S. air defenses removes a potential obstacle to pressure campaigns that have already included cross‑border strikes on what Tehran calls hostile Kurdish elements.

The move fits a wider pattern of Baghdad pushing for the end of foreign missions even as non‑state actors expand their own capabilities. A region that once hosted extensive coalition bases and logistics hubs will now test how far local and federal Iraqi forces can go in filling the vacuum left behind.

The memorable reality for people living in northern Iraq is that when great powers step back, rockets, drones, and the politics of deterrence move closer to their homes. The question is no longer whether the U.S. footprint in Kurdistan is shrinking, but how quickly regional actors will move to fill the space it leaves.

Key signals to watch now include whether Washington announces any residual or over‑the‑horizon arrangements to support Kurdish and Iraqi forces, how Tehran and militia factions respond rhetorically and operationally to the timeline, and whether new security agreements emerge between Erbil and Baghdad to manage the risk of cross‑border strikes once U.S. systems are gone.
