Modern Flag of Afghanistan

Following the Soviet invasion of Afghanistan in 1979, the United States supported both the Afghan resistance fighters and diplomatic efforts to achieve a Soviet withdrawl. As the Taliban rose to national authority in the post-Soviet power vacuum they provided sanctuary for Osama bin Laden. Following the Taliban’s repeated refusal to expel bin Laden and his associates and end its support for international terrorism, the United States and its coalition partners began a military campaign on October 7, 2001, that targeted terrorist facilities and Taliban military and political assets. Kabul fell on November 13, 2001.
