Don't forget to remind them that it was Trump who initiated the pull out. So he kind of boxed Biden in on that one.
Got to think that he should have kept Bagram open until the end though.
This is perhaps more relevant in the other thread, but:
Yes, Trump initiated the pull-out, and in a manner that put all the conditions and onus for action--and restraint--on the US and its allies and none on the Taliban (i.e. he effectively surrendered to the Taliban) while pretending that meaningful concessions had been won from the Taliban.
However, it was a campaign promise from Biden to withdraw militarily from Afghanistan. He also said, on the 19th of February of this year
"My administration strongly supports the diplomatic process that’s underway and to bring an end to this war that is closing out 20 years."

That "diplomatic process" was the US withdrawal in accordance with Trump's surrender agreement.
Since then, his statements on the matter have been contradictory. He has both blamed Trump's deal for the chaotic withdrawal, and also said that the responsibility lies with himself (he said "the buck stops with me").
Despite the timeline imposed by Trump's agreement, Biden actually violated it by extending the deadline for withdrawal from the beginning of May to the end of August. During that period there have been numerous strategic blunders and intelligence failures that have led to the chaos that cannot easily be pinned on Trump.
And perhaps Biden is not entirely to blame either. Yes, he is commander-in-chief, and "the buck stops" with him, as he himself said, but he had reportedly been advised by Chairman of the Joint Chiefs of Staff Mark Milley as recently as July that the Afghan military would be able to hold in the face of the Taliban's advance. Is Biden to blame for the US defence intelligence apparatus being unable to perform its function? The facts on paper about Afghanistan were not facts but falsehoods.
It is perhaps a bit much to expect that the coalition that had been making an absolute shambles of its intervention in Afghanistan for twenty years would be able to withdraw competently and without embarrassment. Instead, we withdrew much as we intervened: making a complete dog's dinner of it.
