Biden's primary problem was that he could not comprehend where the criticism was coming from and would re-frame it in such a way as to absolve responsibility.
Look at the complaints about the Afghanistan evacuation. It was COMPLETELY fucked up and fucked up in ways that were 100% self inflicted.
People tried to tell him, Guam offered to help evacuate civilians, it was all denied under the black and white premise of "Well, we can't stay, we have to get out, what do you want from me?"
Nobody is saying "stay", we're saying look at the order of operations. Can we please get all the civilians out first? Apparently nobody thought of that. Can we not leave behind any usable gear for the Taliban to take over? Yeah, nobody thought of that either.
Look at the complaints about inflation and the economy. Outright denial there was even a problem. Clinton could have told him "It's the economy, stupid!" Biden? "What are you talking about, Jack? We have the best economy in the world! In... the... WOOOOORRLLLLD!"
