Even if true, Biden could do anything he wanted to do.
He could change any policies made by Trump. He could (and did) change the timing. He could have actually planned "contingencies". He could have kept Bagram open. He could have had a coherent communication plan to get the 15,000 Americans out earlier.
It seems like he wanted to shit the bed, all by himself. And he did. Worst policy disaster in a long time...totally on ol' Joe.
Shameful failure. And it continues to get worse due to incompetence from "the pros".
