Biden decided to pull all troops out back in April"
He was told by named military advisors "a complete pullout is not only unnecessary it is sabotage."
In April Biden issued a "conditions ignored withdrawal" which was the same mistake Obama made in Iraq which Bidden also supported.
We could have maintained air support, the airport, and our bases with less than 10,000 personal.
The Taliban has no Air Force at all....until now. But we abandoned that air support and intelligence support, which we promised, and left the Afghani troops to figure it out...they had no chance without US air support. Thousands of NATO troops left also because of the same lack of US air support.
It is not like the US was expected to do the actual front line fighting, the Afghani army was doing all the dying.
