America Is Walking Away From Somalia — And the Mission That Has Held the Line Against Al-Shabaab Is Finished

On July 1, 2026, the United States sent a letter to the African Union.

It was not long. It did not need to be. In diplomatic language that left no room for interpretation, Washington informed the AU Commission that when the mandate of the African Union Support and Stabilization Mission in Somalia comes up for renewal at the UN Security Council in December, the United States will not support its continuation if it includes the UN Support Office in Somalia — the logistical backbone that keeps twelve thousand peacekeeping troops fed, fuelled, transported, and medically supported across four hundred thousand square kilometres of southern and central Somalia.

A senior African diplomat confirmed the letter and described the decision as irreversible, warning that the mission is finished.

The African Union Commission convened an emergency meeting on the future of AUSSOM within days. Without UN logistics, which were funded by the US, we will have to draw a line under our mission in Somalia, the diplomat told AFP, speaking anonymously because he was not authorised to talk to media.

Twenty years of international peacekeeping in Somalia. Nearly three billion dollars in American funding. Twelve thousand troops from Ethiopia, Kenya, Uganda, Djibouti, and Burundi. And now, in a single letter dated July 1, the architecture holding all of it together has been declared over.

What AUSSOM Actually Does

Before assessing what the American decision means, it is worth being precise about what is being withdrawn.

AUSSOM’s 11,826 uniformed personnel, 680 police officers and 85 civilian staff are deployed across five sectors and 49 locations in south-central Somalia, covering an area of about 400,000 square kilometres.

The UN Support Office in Somalia — UNSOS — provides those troops with everything that keeps them operational in the field. UNSOS provides critical logistical support to AUSSOM, including food, fuel, medical services, water, engineering support, and troop transportation.

For the 2026/27 fiscal year, UNSOS operates on an approved budget of about $481.7 million. Without American funding — the US covers about 26 percent of the UN’s budget through assessed contributions — that budget collapses. Without that budget, the mission cannot function.

This is not a funding shortfall that can be patched with emergency contributions. It is a structural withdrawal from the financial architecture that has sustained the entire operation.

Why Washington Says It Is Leaving

The American letter did not mince words about its reasoning. The US stated that despite more than a decade of international support, Somalia has been unable to sustain progress against al-Shabaab, take ownership of its security functions, or undertake serious security sector reform. It went on to state that internal rivalries and political infighting continue to undermine the fight against al-Shabaab and ISIS, and the benefits of international support will remain limited until Somalia’s leaders unite to address the country’s security and governance challenges.

A US State Department spokesperson said Washington has contributed nearly $2 billion to UN support operations in Somalia but argued that the Somali government has not made sufficient progress in assuming responsibility for the country’s security despite years of international assistance.

The indictment is harsh. It is also, in significant respects, accurate.

Somalia’s federal government has spent the past year consumed by a political crisis of its own making. President Hassan Sheikh Mohamud had the constitution changed earlier this year, extending his term by a year after it expired on May 15 — a move that has deepened divisions between Mogadishu and the federal member states, particularly Puntland and Jubaland, at precisely the moment that unified political leadership was needed to sustain the security effort. Al-Shabaab’s military offensive, which made striking gains in 2022, has stalled. The group continues to hold territory, collect taxes, and carry out complex attacks in Mogadishu and other urban centres.

The American frustration is real and documented. Since 2024, the US has opposed efforts by the AU, the UN and other traditional donors to finance AUSSOM under UN Security Council Resolution 2719, which proposed using UN-assessed contributions to cover 75 percent of the mission’s annual budget. Washington’s threat last year to veto the proposal in the Security Council effectively extinguished hopes that the mechanism would provide the mission with timely, adequate and predictable funding.

July 1 was not a surprise. It was the culmination of a policy direction that has been building for two years.

The Financial Crisis That Was Already There

The withdrawal comes on top of a mission that was already in serious financial difficulty before the American letter arrived.

Financially, despite the conservative $166.5 million budget of the mission for the June 2025 to July 2026 period, only a fraction of the budget was raised, even after various efforts. To make matters worse, AUSSOM inherited substantial debt from its predecessor. Outstanding arrears owed to troop-contributing countries from 2022 to 2024 amount to $93.9 million.

In April 2026, the EU announced a €75 million funding package for AUSSOM’s military component, ending two years of negotiations to restore funding for the mission. That was a significant contribution — but it addressed the military component, not the UNSOS logistics package that the American decision has now removed.

The mathematics are unforgiving. Following the communication from the US and the resultant near unviability of AUSSOM without UNSOS, any amount of manoeuvre on the part of the AU is unlikely to save the mission beyond December 2026.

What Happens When AUSSOM Ends

The question that every security analyst covering Somalia is now asking is the one that the AU’s emergency meeting has not yet answered: what happens to the territory AUSSOM currently holds when the mission withdraws?

The Somali National Army — the force that AUSSOM exists to support and that is supposed to eventually replace it — is not ready to hold that territory alone. It has never been ready. The entire international effort in Somalia has been premised on a timeline in which Somali forces gradually assume responsibility as their capacity grows. That timeline has consistently slipped. The slow pace of mobilisation and deployment of Somali security forces has been the centre of major concern.

Al-Shabaab knows this. The group has demonstrated, repeatedly, that it is capable of reclaiming territory that government and AU forces abandon. It has governed rural areas for years through a combination of taxation, dispute resolution, and violence, building an administrative presence that is harder to dislodge than a military position.

A rapid or disorganised withdrawal of AUSSOM without a credible Somali force to replace it would create security vacuums across southern and central Somalia that al-Shabaab is strategically positioned to fill. The areas most at risk are precisely the ones where the international effort has made the most progress over the past decade — territory that took years to liberate and that could be lost in months.

The Regional Consequences

The implications extend well beyond Somalia’s borders.

For Kenya, AUSSOM’s largest single troop contributor, the end of the mission raises immediate questions about what happens to Kenyan forces currently deployed inside Somalia, and whether Nairobi is willing to sustain that presence without American logistical support. Kenya’s involvement in Somalia has always been partly about managing its own security — keeping al-Shabaab away from its northeastern border and reducing the threat to its tourism sector, which has been repeatedly struck by the group’s cross-border attacks. Those interests do not disappear when American funding does.

For Ethiopia, whose deployment under AUSSOM was part of the complex diplomatic resolution of the Somalia-Ethiopia crisis triggered by the Somaliland port access deal, the end of the mission raises questions about whether Ethiopian forces will remain, under what framework, and whether their presence will continue to be acceptable to a Somali government that spent the better part of 2024 treating Ethiopia as an existential threat.

For Turkey, whose Camp TURKSOM trains Somali forces and whose combat troops have now engaged al-Shabaab directly, the American withdrawal creates both a challenge and an opportunity — a challenge because the security environment deteriorates, an opportunity because the space vacated by American strategic engagement is exactly the kind of space that Ankara has been filling across the Horn of Africa for a decade.

And for Egypt, which has been deploying forces to Somalia under its own bilateral defense agreement and building military relationships with Mogadishu as a counterweight to Ethiopian influence, the collapse of AUSSOM potentially accelerates a dynamic in which Somalia’s security architecture becomes dominated by bilateral relationships with regional powers rather than by the multilateral AU framework — a development that serves Egyptian interests in weakening Ethiopia’s position in Somalia.

What Somalia’s Government Must Do — And Has Not

The American letter is a rebuke. But it is a rebuke that Somalia’s own leaders have provided ample justification for.

A government that spends the year of its most significant security crisis consumed by constitutional manipulation to extend a presidential term, that fails to resolve the political standoff with Puntland and Jubaland that has left the federal system functionally broken, that negotiates separately with Turkey, Egypt, Saudi Arabia, and the UAE without articulating a coherent national security strategy that any of those partners is being asked to serve — that government has not earned the continued patience of a donor that has spent three billion dollars over twenty years.

The American diagnosis is harsh and politically convenient for a Trump administration that has been systematically withdrawing from multilateral commitments globally. But the structural failure it describes is real. Somalia cannot continue to outsource its security indefinitely to a rotating cast of foreign armies, each pursuing its own strategic interests, while its own political class remains locked in the kind of elite competition that al-Shabaab has always fed on.

What Comes Next

It is anticipated that the letter from the US could trigger the convening of an urgent meeting of the troop-contributing countries and the AU Peace and Security Council. On July 3, the AU’s Peace Support Operations Division convened an information briefing for the Defence Attachés of the troop-contributing and police-contributing countries of AUSSOM.

The options available to the AU are limited. Finding an alternative funding mechanism for a $481 million logistics operation in the months before December’s Security Council deadline is not a realistic prospect. The EU’s €75 million contribution covers the military component but not UNSOS. Gulf states that have funded AU operations in the past are currently consumed by their own regional rivalry. China, which has a base in Djibouti and growing interests in the Horn, has not historically funded AU peacekeeping at the scale that would be required.

The most likely outcome is not an orderly transition but a managed contraction — a mission that shrinks, consolidates into fewer locations, and gradually transfers responsibility to Somali forces that are not yet capable of bearing it. Whether that contraction can be managed without creating the security vacuums that would allow al-Shabaab to expand is the question on which Somalia’s immediate future depends.

Twenty years ago, the African Union deployed its first troops to Mogadishu to prevent a country from being consumed entirely by an insurgency. The mission has cost enormous sums, enormous political effort, and the lives of thousands of soldiers. It has not solved Somalia’s problems. But it has held a line.

On July 1, America decided it was done paying for that line to be held.

What comes next will be determined by whether Somalia’s leaders can, for the first time in two decades, begin to hold it themselves.
