POSITION TOWARDS THE CONFLICT
In March 2015, Saudi Arabia established a coalition of nations to engage in military operations in Yemen against the Ansar Allah/Houthi movement and loyalists of the previous president of Yemen, the late Ali Abdullah Saleh. During 2014, the United States joined Saudi Arabia in demanding that Houthi forces reverse their unilateral military campaign to occupy the Yemeni capital of Sanaa, but the rapid onset of hostilities in March 2015 forced the Obama Administration to react quickly. At the start of the Saudi-led intervention on March 25, 2015, the Administration announced that the United States would provide “logistical and intelligence support” to the coalition’s operations without taking “direct military action in Yemen in support of this effort.” Soon thereafter, a joint U.S.- Saudi planning cell was established to coordinate military and intelligence support for the campaign.
At the United Nations Security Council, the United States supported the passage of Resolution 2216 (April 2015), which, among other things, required member states to impose an arms embargo against the Houthi-Saleh forces and demanded that the Houthis withdraw from all areas seized during the current conflict. The Trump Administration has opposed various congressional proposals, including initiatives to reject or condition proposed U.S. arms sales or to require an end to U.S. military support to Saudi-led coalition operations in Yemen.
