when did us go to war in afghanistan
War in Afghanistan (2001–present) The War in Afghanistan (or the U.S. War in Afghanistan; code named Operation Enduring Freedom – Afghanistan (2001–2014) and Operation Freedom's Sentinel (2015–present))[50][51] followed the United States invasion of Afghanistan[52] of October 7, 2001. The U.S. was supported initially by the United Kingdom and Canada[53] and later by a coalition of over 40 countries, including all NATO members. The war's public aims were to dismantle al-Qaeda and to deny it a safe base of operations in Afghanistan by removing the Taliban from power.[54] The War in Afghanistan is the second longest war in United States history, behind the Vietnam War.[55][56][57][58][59]
