Try to get this through your head.... the operable equipment the Taliban now has, was the property of the Afghan military, sold or otherwise provided to them over three Presidential administrations, beginning with George W. Bush.
Any equipment that belonged to the US was rendered inoperable prior to leaving.
Blaming Biden for not retrieving it all or destroying it, is fucking stupid if, for no other reason than that it was assumed the Afghan military would continue to use it as they continued to fight for their own country.
The fact that they folded and fell apart like a cheap suit is another issue altogether.
At any rate, the US will probably end up destroying all or most of that equipment in future drone strikes on the Taliban anyway.
Future drone strikes? So we ain't leaving anyway?
