Ignorant. You picked up a date you don't understand. Doha Accord signed by US & Taliban says

The US agreed that US would have an immediate reduction of military force within 135 days from the signing date of the accord. After finishing 1st reduction of 135-day, US would finish full withdrawal within 14 months if the Taliban keep its commitments. This, 135 days+14 months, leads to the May 1st as the last day of this withdrawal. There was no such a thing as Trump claimed May 1st as deadline fir military withdrawal operation. In another word, your diplomatic agreement allows your military to stay 14 months + 135 days in Afghanistan since signing day, but that doesn't mean your plan is going to take 14 months + 135 days, i.e you pulled out last solider on April 30.

The point is, as we know Taliban didn't keep its commitments during those 14 months. The original 14-month promise made in Doha accord doesn't have to be kept and actually US didn't. So, without restriction of withdrawal deadline it's supposed to be more flexible for Biden to plan on withdraw from Afghan. Again he doesn't have to give deadline or he can give a false deadline which is longer than US need to withdraw. He didn't choose either. Stupid. And you, ignorant and clueless about the whole situation.
