U.S. Troops Leave Iraq After 23 Years—Baghdad Celebrates, But the Next Power Struggle Starts Now

The United States formally withdrew its forces from Iraq on 2026-09-30, ending a military presence that followed more than two decades of war and coalition operations. Iraqi officials and commentators framed the move as a defense of sovereignty after the U.S.-led international coalition concluded its mission. In Baghdad, the withdrawal triggered visible celebrations, but it also immediately raised questions about who will fill the security and political vacuum. Analysts interviewed by PBS, including James Jeffrey and Feisal Istrabadi, emphasized that the end of the U.S. footprint does not automatically translate into stability for the region. Strategically, the departure shifts leverage away from Washington and toward local and regional actors that have long competed for influence in Iraq. The U.S. exit can benefit Baghdad’s sovereignty narrative, but it also reduces deterrence and intelligence-sharing capacity that previously helped manage militia activity and cross-border threats. The power dynamic now hinges on how Iraq coordinates with remaining partners, how internal factions recalibrate, and whether external stakeholders attempt to expand their role under the banner of “security assistance.” The United Nations is referenced in the analysis context, underscoring that international legitimacy and monitoring will matter as the security architecture transitions. Market and economic implications are likely indirect but potentially meaningful through risk premia rather than immediate commodity disruptions. Iraq’s security transition can affect investor sentiment toward Iraqi sovereign and corporate risk, and it can influence regional energy and logistics expectations by altering perceived stability along key routes. In the near term, traders may price higher volatility in regional risk assets and in instruments tied to Middle East security, even if crude flows are not yet disrupted. The most immediate “direction” is therefore toward higher risk premiums for Iraq-linked exposures and regional insurers, with magnitude dependent on how quickly militia behavior and cross-border incidents normalize. What to watch next is whether the post-withdrawal period produces a measurable change in attacks, militia posture, and government control over key security institutions. Key indicators include incident frequency around Baghdad and other strategic areas, statements from Iraqi leadership on security arrangements, and any renewed diplomatic engagement between Washington and Baghdad in non-military formats. A trigger for escalation would be a rapid deterioration in internal security or a surge in attacks targeting infrastructure and diplomatic sites, which could force ad hoc external responses. De-escalation would look like sustained restraint by armed groups, credible integration of forces under Iraqi command, and progress on diplomatic frameworks that preserve intelligence and crisis communication channels.

Geopolitical Implications

• 01

  Washington’s reduced footprint changes the balance of influence among Iraqi factions and regional stakeholders, increasing the likelihood of a contested security transition.

• 02

  Baghdad’s sovereignty narrative may strengthen domestically, but it also raises expectations for rapid stabilization that could be difficult without external support.

• 03

  The UN’s role in legitimacy/monitoring becomes more salient as the international military architecture transitions to a political-security framework.

Key Signals

• —Frequency and location of attacks or militia activity in the weeks after withdrawal, especially around Baghdad and critical infrastructure.
• —Public statements by Iraqi authorities on security arrangements, command integration, and any continued intelligence cooperation.
• —Regional actors’ messaging about “support” and whether it translates into operational presence or only diplomatic engagement.
• —Any UN-related reporting or monitoring updates tied to stability, human rights, or protection of civilians.
