The Obama Administration and several of its partner countries are seeking to reduce U.S. military involvement in Afghanistan while continuing to build Afghan governing and security capacity to defend the country by the end of 2014. To secure longer term U.S. gains, on May 1, 2012, President Obama signed a Strategic Partnership Agreement that will likely keep some (perhaps 15,000-20,000) U.S. troops in Afghanistan after 2014 as advisors and trainers. Until then, the United States and its partners will continue to transfer overall security responsibility to Afghan security forces, with Afghan forces to assume the lead nationwide by mid-2013. As lead responsibility shifts, the number of U.S. forces in Afghanistan, which peaked at about 100,000 in June 2011, has been reduced to the "pre-surge" level of 68,000 as of September 20, 2012. President Obama has said that "reductions will continue at a steady pace" from then until the completion of the transition to Afghan lead at the end of 2014. However, the transition process has been hampered somewhat by a pattern of attacks by Afghan forces on their coalition mentors and trainers. In keeping with the Strategic Partnership Agreement, on July 7, 2012 (one day in advance of a major donors' conference on Afghanistan in Tokyo) the United States named Afghanistan a "Major Non-NATO Ally," further assuring Afghanistan of longterm U.S. support.
