U.S. mission in Afghanistan

The main mission of U.S. in Afghanistan was to killed Bin Laden. Osama Bin Laden sent terrorists to attack the US on September 11, 2011. After the attack, US demanded Afghanistan turn Bin Laden over to the US to stand trial but Afghanistan supports Bin Laden and refused to turn him over so the US President George W Bush launches a operation called "Enduing Freedom". Ever since then the Us and Taliban have been fighting. Many counties have join to help the US.
