All Trump did was agree to the removal and set the timeline. The actual EXECUTION of the removal was on Biden because, by the time it actually came to get out, Biden was the commander in chief.
He SHOULD have evacuated all civilians and Afghani assets first, he failed to do that, even when Guam stepped up and offered to assist going “Hey, you know we’ve done this before, right?”
Once you evacuate all the civilian assets, you remove all the gear and equipment you can, then you burn the rest.
THEN you bring the troops home.
Point for point, Biden screwed it up, and when he gets called out on it, his argument is “Well, hey, we had to leave…” and while he’s not wrong in that, the priority and methodology was fucked from the ground up.
