It is astounding to me that some of the lefties in this thread can't help but point to Trump.
ALL presidents inherit problems from their predecessors. Trump inherited a bad Iran deal and N. Korea, not to mention an aggressive China that Obama had no appetite to confront. This is not a defense of how Trump dealt with those issues. For purposes of this discussion, it is irrelevant. It is merely to point out that all presidents are faced with these issues and are responsible for how they act once they take office.
Upon taking office, Biden reversed innumerable Trump policies and agreements (as Trump did when he exited the Iran deal and trans pacific agreement). He isn't shy about it. If Biden didn't like the deal Trump cut with the Taliban, he could have exited it. Trump's deal (whatever you think of it) had conditions that were not met - Biden could have revoked it or repudiated it. Even the AP says that.

He made an affirmative choice to leave - it had almost nothing to do with Trump. And, for purposes of this discussion, the merits of Biden's choice are a different discussion. But pinning this on Trump and his agreement is both dishonest and absurd - read the AP article I linked to.
Having decided to leave, Biden is 1000% responsible for how the exit occurred. And the damage of his lie (that the taliban would not take over) is that it prevented US civilians, contractors, allies and friendly Afghanis from preparing for a timely exit. Those defending or rationalizing the lie (Sycasey) ignore this fact. People will die because of that lie that wouldn't have otherwise.
There was no reason to close Bagram. There was no reason to discontinue air support for the Afghan army. It is a bit off topic, but the US spent 20 years training the Afghan army to fight like we do - with massive air support and intelligence gathering. Then we took that away and wonder why the Afghans couldn't fight?
Biden has botched this beyond belief. His behavior is inexplicable - not coordinating with our closest allies, not listening to the intelligence he was given (or ignoring and lying about it), allowing the Taliban to obtain possession of all of the military equipment, not calling Boris Johnson back for 36 hours in the midst of the crisis, etc. Withdrawing troops before evacuating citizens.
And most shamefully, his administrations has refused to unequivocally state they will protect all US citizens in Afghanistan. That is truly unprecedented and an abrogation of Biden's most basic duty.
