Iraq Faces Sovereignty Test as US-Led Coalition Withdrawal Nears

Iraq is approaching a major turning point in its security policy as the United States-led international military coalition prepares to formally end its mission in the country on September 30.

Iraqi military officials have confirmed that the coalition's mission will conclude at the end of the month, marking the beginning of a new phase of security and diplomatic cooperation between Baghdad and Washington.

Lieutenant General Abdul Amir al-Shammari, director of the Office of the Commander-in-Chief of the Armed Forces, told the Iraqi News Agency that September 30 would be the final date for the coalition's military mission and the start of a new chapter in relations with its members.

The announcement was also confirmed by Prime Minister Ali al-Zaidi's security adviser, Qasim al-Araji.

The withdrawal follows a 2024 agreement between Iraq and the United States. As part of the process, American air-defence systems stationed in Erbil, the capital of Iraq's autonomous Kurdistan region, are also due to be removed.

Those systems, including Patriot missile batteries, have played an important role in protecting the region from ballistic missiles and drones during the ongoing conflict involving Iran, the United States and Israel.

The United States invaded Iraq in 2003, triggering years of conflict and sectarian violence that killed an estimated 200,000 civilians. American forces withdrew in 2011 but returned in 2015 as part of an international coalition established to fight ISIL, also known as ISIS.

The Iraqi prime minister's office said September 30 would be the "fixed and final date" for ending the coalition's military mission against ISIL and completing the departure of its forces.

It described October 1 as the beginning of a new era in which Iraq would no longer have a foreign military presence, calling the development an important step towards national sovereignty, development and economic prosperity.

Domestic Security Challenges

Despite the planned withdrawal, Iraq faces significant internal security challenges, particularly over the government's efforts to bring all weapons under state control.

Prime Minister al-Zaidi has reaffirmed a September 30 deadline for non-state armed groups to surrender their weapons or potentially face terrorism-related charges.

University of Baghdad political science professor Iyad al-Anbar said the American withdrawal was largely symbolic because the US military has already reduced its presence at several major Iraqi facilities.

He said the bulk of the remaining American military presence had become concentrated at Harir base near Erbil, while US forces had already departed or reduced their role at locations including Camp Victory near Baghdad airport and facilities around the Green Zone.

However, the government's attempt to bring armed groups under state authority remains politically sensitive.

Al-Anbar said the government had increasingly used the term "regulating" weapons rather than simply demanding their removal, raising questions about how the policy would actually be implemented.

He also pointed to increasingly confrontational rhetoric from groups including Kataib Sayyid al-Shuhada, Harakat al-Nujaba and Kataib Hezbollah.

The government faces an additional challenge because key positions within Iraq's defence and interior ministries remain vacant. Those ministries will be central to any effort to establish greater state control over armed forces operating outside the government's direct authority.

Washington's Strategic Shift

The end of the coalition's military mission does not necessarily mean the United States is abandoning Iraq.

Former US diplomat Marlin Hardinger said Washington was likely to maintain a security relationship with Baghdad, particularly through counterterrorism and intelligence cooperation.

He suggested that US personnel could continue operating around the American embassy and consulate, while the Trump administration may place greater emphasis on economic and development initiatives.

A stronger economic relationship, Hardinger said, could help strengthen the Iraqi government's position domestically while allowing Washington to maintain influence without a large military footprint.

The withdrawal is likely to appeal to supporters of President Donald Trump's "America First" approach, which has generally favoured reducing long-term US military commitments overseas.

But the decision could also concern regional allies who believe American military power remains necessary to counter threats in the Middle East.

Hardinger warned that the broader regional environment has become significantly more unstable since negotiations over the US withdrawal began.

Concerns Over Air Defence

The removal of American Patriot systems is generating particular concern in northern Iraq.

Hassan al-Barari, an international relations professor at the University of Jordan, said Iraq currently lacks the capability to adequately defend its airspace against a sustained missile or drone attack from Iran.

He questioned who would intercept Iranian missiles or drones targeting Erbil if American air-defence systems were removed.

The issue becomes more complicated if Baghdad and Tehran cannot establish an effective understanding over future security threats.

Ultimately, analysts say, Iraq's ability to maintain sovereignty will depend on more than the departure of foreign troops.

Baghdad will need to demonstrate that it can independently protect its territory while establishing a state monopoly over weapons and preventing armed factions from operating outside government authority.

Al-Barari warned that failure to achieve those objectives could leave Iraq facing a dangerous security vacuum and potentially increase Iran's influence over the country.

For Iraq, the September 30 withdrawal therefore represents both a milestone in reclaiming greater control over its security affairs and a significant test of whether the government is prepared to manage those responsibilities on its own.
