The Taliban has swiftly regained control of Afghanistan 20 years after US forces began Operation Enduring Freedom (OEF).
The United States linked the September 11, 2001 terrorist attacks to al Qaeda, a group that operated under the Taliban regime’s protection in Afghanistan. The operation was launched to stop the Taliban from providing a safe haven to al Qaeda and to stop al Qaeda’s use of Afghanistan as a base of operations for terrorist activities.
Operation Enduring Freedom began on October 7, 2001, under President George W. Bush’s administration, with allied air strikes on Taliban and al Qaeda targets.
On Oct. 14, 2001, the Taliban offered to discuss giving al Qaeda leader Osama bin Laden to a third country for trial if the United States provided evidence of bin Laden’s involvement in the Sept. 11 attacks. The White House rejected the offer.
On Nov. 13, 2001, US airstrikes and ground attacks by the anti-Taliban Afghan Northern Alliance led to the fall of Kabul.
That same month many European countries offered troops to support OEF including, Germany, the Netherlands, France and Italy. US Defense Secretary Donald Rumsfeld also announced that the US had doubled the number of its troops based in the country.
