The only different between Trump and Biden is the time of withdrawal from Afghanistan.
Had Trump won the election, the troops and ambassador+crew had left end April/May.
If there had been chaos at the airport if Trump had been in charge ? Very likely.
Remember it's not who's the President but the mentality of the Afghan people. They want to escape their country and they want to do so whether it's in April/May or Aug.
