Ultimately nobody wanted to take the L on that one, this goes back to Obama too. Everyone knew how fast it would fall and how bad it would look and when it was put on the table they delayed it, Trump included. IMO it’s one of the best things Biden did and showed his integrity on the topic, he was willing to be the loser and think about others, and go against the interests of the military contractors etc.

Biden actually took full credit and responsibility for that on a few occasions, I think he explicitly stated “this responsibility rests with me and me alone” or something to that effect. So “blaming” Trump for this good thing is ironically giving Trump credit.
