Editor's Note: A previous version of this assessment incorrectly stated that Afghanistan had 407 districts instead of 421. It has been updated accordingly. The rapid withdrawal of foreign troops from Afghanistan, combined with the Taliban’s recent territorial gains, will create a power struggle between the Taliban and the Afghan government that will likely cause a civil war and further degrade the regional security environment. The Sept. 11 deadline for the withdrawal of U.S. troops announced by President Joe Biden has become a symbolic timeline. On the ground, more than half of U.S. and NATO troops have left Afghanistan, and reports suggest remaining troops will leave the country as soon as the first week of July. On July 2, U.S. forces finished withdrawing from Bagram, their main military base in Afghanistan.
