Twenty years after the terrorist attacks carried out by Al-Qaeda which left nearly 3,000 dead in the United States, the last American troops have just left Afghanistan as a matter of urgency. Over 800,000 US troops have been deployed to Afghanistan since 2001. Was it time to leave the country? What will the departure of the Americans entail? What consequences for the Afghans? These questions are divisive among Americans whose lives have been deeply marked by this conflict.
