The U.S. program of assistance to Afghanistan is intended to stabilize and strengthen the Afghan economic, social, political, and security environment so as to blunt popular support for extremist forces in the region. Since 2001, nearly $48 billion has been appropriated toward this effort. More than half of "U.S. assistance--roughly 57%--has gone to the training and equipping of Afghan forces. The remainder has gone to development and humanitarian-related activities from infrastructure to private sector support, governance and democratization efforts, and counternarcotics programs. Key U.S. agencies providing aid are the Department of Defense, the Agency for International Development, and the Department of State. In December 2009, Congress approved the FY2010 State, Foreign Operations appropriations (H.R. 3288, Division F, P.L. 111-117), providing $2 billion in the Economic Support Fund (ESF) and $420 million in the International Narcotics and Law Enforcement (INCLE) accounts. It also approved the FY2010 DOD appropriations (H.R. 3326, P.L. 111-118), providing $6.6 billion to the Afghan Security Forces Fund (ASFF) and allocating $1 billion for the Commander's Emergency Response Program (CERP) activities in Afghanistan."
