War in Afghanistan
The War in Afghanistan (or the U.S. War in Afghanistan), code named Operation Enduring Freedom – Afghanistan (2001–14) and Operation Freedom’s Sentinel (2015–present), followed the United States invasion of Afghanistan of 7 October 2001. The U.S. was initially supported by the United Kingdom, Canada, and Australia 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. Since the initial objectives were completed at the end of 2001, the war mostly involves U.S. and allied Afghan government troops battling Taliban insurgents. The War in Afghanistan is the longest war in U.S. history.
