The blocking by the US of UN funding to African Union (AU) forces in Somalia starting next year is a body blow to a mission that has long been on financial life-support. The UN Support Office in Somalia (UNSOS) provides the logistical backing critical to the functioning of the AU mission. Without that underpinning, it's hard to see how the AU's 11,800-strong force can continue. That became evident when Washington vetoed the application to Somalia of UN Resolution 2719 on peacekeeping cost-sharing. The AU's near two-decade mission has done significant work. Despite heavy casualties, it succeeded in ousting al-Shabab from Mogadishu—a daunting task the UN and the rest of the international system was unwilling to take on—and continued to protect Somalia's fractious political elite from the jihadist insurgency. But the inability of Somalia to grow and deploy its own security forces to consolidate territorial gains secured by the AU resulted in deadly mission creep and effectively tore up any putative exit plan. Instead, the AU has soldiered on in the absence of a workable political strategy, and with ever-shrinking sources of financing.
