How much money has been spent?
The vast majority of spending in Afghanistan has come from the US.
Between 2010 to 2012, when the US for a time had more than 100,000 soldiers in the country, the cost of the war grew to more than $100bn a year, according to US government figures.
As the US military shifted its focus away from offensive operations and concentrated more on training up Afghan forces, costs fell sharply to about $45bn in recent years.
According to the US Department of Defense, the total military expenditure in Afghanistan (from October 2001 until December 2020) was $825bn, with about another $130bn spent on reconstruction projects.
That brings the total cost, based on official data, to about $955bn between 2001 and 2020 - close to the lower $1tn by Mr Biden.
