On August 15, 2021, Afghanistan descends into chaos. In one day, the completion of the withdrawal of Western forces precipitated the debacle of the regime in place: the army vanished, the leaders fled and the Taliban took Kabul without a fight. The great Central Asian country opens a new chapter in its tragic history, twenty years after the "war on terror" launched by George W. Bush in response to the attacks of September 11, 2001. The undisputed masters of 40 million trapped Afghans, the "students of religion" are back and are savoring their revenge by posing as the United States' victors. Their program will surprise no one: to restore the Islamic emirate and set up the "true" sharia, i.e. a perfect world, with divine commandments applied to the letter as in the time of the prophet.
