The United States spent an estimated $2.26 trillion on the war effort in Afghanistan – only to see its two-decade project dismantled in the blink of an eye. It took the Taliban just 10 days to take over the government in Kabul after sweeping across the countryside. The group seized its first provincial capital — Zaranj in Nimruz province, on the border with Iran — on August 6. By August 15, the Taliban had captured Kabul without a fight, stunning the world.

Here is a look at the cost in lives, dollars and resources spent in Afghanistan since 2001, when the United States took the fateful decision to invade the country.
