Only way we get rid of the Taliban is to round them up and start gassing. But ummm we don't do that. So, seeing as how the Taliban are there we have to negotiate, including the two leading Afghan political parties who at the time are not inclined to invite the Taliban to the table. Either they start working together or we stay past May 1st. By 'we' I mean NATO and U.S. forces as both Biden and NATO Secretary General Jens Stoltenberg have stated. Europe has just as much an interest in a stable Afghanistan as anyone else.
I want to add that its not just the U.S. which open to negotiation with the Taliban either.
