from a Taliban that held all the cards that Trump gave away...I seriously doubt that the Taliban would go along with an extension that went beyond September and into the winter 'non-fighting season' there...worsening conditions in June and July due to rapid Taliban advances caused the six week move up in exit plans...that's my take...
btw, when you start cursing, you show your weakness...accept the fact that Trump made a bad situation much worse by taking steps that harmed our most treasured Afghan allies...Biden is doing all he can to rise above those impediments...the recent Bill is ample evidence of that.
