We could have given close air support, but Old Joe abandoned our base at Bagram so we would have to depend on carrier based planes. Joe also could have called in B-52 raids or A-10s but chose to bug out in the middle of the night leaving billions in weapons to the Taliban
The Taliban is now in possession of Blackhawks and Azerbijan has some more, courtesy of the Afghani air force. After 20yrs, they should have been flying their own close air support.
There is no excuse for the Afghan army collapse.
Not even A10s or b52s could have helped.
