On Wednesday, United States President Joe Biden announced the complete withdrawal of all American troops from Afghanistan by September 11, the twentieth anniversary of the attacks on New York and Washington that resulted in the US-led military invasion.

Assessments from US intelligence agencies in recent months found that a withdrawal in the absence of an intra-Afghan peace deal would likely lead to the collapse of the government in Kabul within a couple of years and the potential resurgence of al-Qaeda in the country.
