When the Taliban was in the open, on the move to Kabul, he would have wiped them off the face of the Earth.
Next, he would have not surrendered Kandahar airbase. He would have kept air power in Afghanistan until it was no longer needed.
He would have evacuated ALL civilians. He would not have retreated and given up any ground before the evacuation was complete. He would not have let the Taliban set up check points. That would be a non starter.
Next, he would have removed all of OUR military gear. How the hell do we not fly 4 big C-130 transports out of the country?
Any military equipment captured by the Taliban would have been destroyed by airstrikes or artillery.
When the French are making fun of your retreat you might have done something wrong. When the local goat herder pedophiles embarrass the biggest super power you might have done some thing wrong.
Of course one can start with what every single general outside the Biden admin is saying that Bagram airport and the 400 close ground support aircraft shouldn’t have been evacuated until the civilians were. I have seen zero generals say anything differently on the subject.
