Why did the U.S. become involved in Afghanistan?
Liono4ka [1.6K]

The narrative and goals for what has become America’s longest war have shifted in the past 16 years, and they may take a new turn Monday night, as President Donald Trump is expected to announce his policy approach for Afghanistan.The war started in October 2001 in the wake of the September 11th attacks, under then-President George W. Bush, and after Obama, Trump is now the second president to inherit -- and have to make a decision on how to handle -- the ongoing conflict.

When Bush first announced the military action on Oct. 7, 2001, he described “strikes against al Qaeda terrorist training camps and military installations of the Taliban regime in Afghanistan.”
