War in Afghanistan: Strategy, Military Operations, and Issues for Congress [May 6, 2010] [open pdf - 2MB]
"Since 2001, the character of the war in Afghanistan has evolved from a violent struggle against al Qaeda and its Taliban supporters to a multi-faceted counterinsurgency (COIN) effort. In the aftermath of the terrorist attacks of September 11, 2001, the United States launched Operation Enduring Freedom (OEF) in order to end the ability of the Taliban regime to provide safe haven to al Qaeda and to put a stop to al Qaeda's use of the territory of Afghanistan as a base of operations for terrorist activities. In that first phase, U.S. and coalition forces, working with Afghan opposition forces, quickly removed the Taliban regime. [...] In his December 3, 2009, speech President Obama identified several objectives in Afghanistan and Pakistan: (1) disrupt, dismantle, and defeat al Qaeda; (2) deny al Qaeda a safe haven; (3) reverse the Taliban's momentum and deny it the ability to overthrow the government; and (4) strengthen the capacity of the Afghan security forces and government to better protect and serve population centers. To accomplish this, President Obama ordered the deployment of an additional 30,000 troops to the region, which will bring the U.S. total to almost 100,000 troops. This deployment will be staged over several months, with the full additional complement being in-country by the end of the summer 2010. Noting that Afghan operations continue to be an international effort, President Obama expressed confidence that some of 42 coalition allies will also be increasing their contributions. NATO [North Atlantic Treaty Organization] Secretary-General Rasmussen echoed this confidence, stating that he expects NATO allies to contribute at least an additional 5,000 troops in 2010."
