New Authorization for Use of Military Force Against the Islamic State: Issues and Current Proposals [January 15, 2016] [open pdf - 794KB]
"In 2014, the armed offensive of the Islamic State (also known as ISIL, ISIS, or Daesh) in northern and western Iraq and northeastern Syria raised significant concerns for the United States. After first ordering multiple deployments of U.S. troops to Iraq to provide security to diplomatic personnel and facilities, advise Iraqi security forces, and conduct intelligence gathering and reconnaissance, President Obama began ordering U.S. military airstrikes on IS forces in Iraq in August 2014. Later in September, after laying out plans for expanded use of military force against the Islamic State in a televised speech to the American people, the President ordered U.S. military airstrikes in Syria against both IS forces and forces of the 'Khorasan Group,' identified by the President as part of Al Qaeda. In 2015, the President ordered new deployments to Iraq, and the Administration announced deployment of a small number of special operations forces to Syria to conduct military operations that involve advising regional partner armed forces but also can include 'unilateral' U.S. operations. [...] This report focuses on the several proposals for a new AUMF [authorization for use of military force] specifically targeting the Islamic State made druing the 113th and 114th Congress."
