The character of the war in Afghanistan evolved from a violent struggle against al Qaeda and its Taliban supporters to a multi-faceted counterinsurgency (COIN) effort. This report provides an examination of the war's background, context, and early execution; an analytical discussion of the COIN war to date, including strategy, organization, participation, and key facets of the effort including population security, advising the Afghan National Security Forces (ANSF), counter-narcotics, reconciliation, community outreach, and civil-military coordination; and an analysis of major strategic and operational issues and options that the 111th Congress may opt to consider.
