The powerful bomb blast attack by an ISIS affiliate, ISIS-K (Khorasan), a deadly terror group of jihadists from Syria and other areas, on American forces and Afghan civilians in Kabul on August 26, 2021, killed 13 U.S. troops and more than 90 Afghans. This was a dark day for the U.S., the deadliest day for U.S. military forces in Afghanistan since 2011. Internal and international controversy will continue and mount over the debacle in Kabul and responsibility. President Biden has declared that the “buck stops” with him. But the mistakes of his administration are more compelling than the rhetoric: the debate will continue on the hasty exit timetable for the U.S. from Afghanistan; on the disagreements among U.S. military leaders and the president on withdrawal; on Biden’s abrupt abandonment of Bagram Airbase, which could have been used for evacuation of Americans; alleged sharing of security arrangements; giving a list to the Taliban of Afghans who aided the U.S. It is a notable lack of success in a country with remarkable assets: 150 countries host U.S. troops, 200,000 U.S. troops are located abroad, annual military spending is $770 billion, and the fleet has 11 aircraft carriers.
