Biden and Trump plan would have removed all troops by Sept 11 anyway.
Yes but that is some psychological warfare going on.
What a feather in your taliban hat to crow how you brought the mighty US to their knees by the anniversary of the bombing.
Plus..it helps jack up the price per person that you will allow out of the country by that date.
This change in date plus abandoning Bagram airbase without notice to Afghan government or military several weeks before the evacuation are the two biggest blunders Biden has made. I do not know why politicians and media supposedly on our side do not mention these two aspects of the bungled evacuation.
