Biden is responsible for his decision to override the advice he received when he ordered the withdrawal. That he pulled the military element out before securing the diplomatic infrastructure is beyond words. Those errors have led to there being more troops in Afghanistan now then when the withdrawal started. Is Biden responsible for that? According to Biden, yes. He said so: "I am president of the United States of America, and the buck stops with me." Good for him for clearing that up for some of you.
He should also get the credit for cutting our losses going forward. I think it will prove to be the right decision in time, but the manner of what you do also matters. This withdrawal was a failed execution. You can do the right thing the wrong way.
What is the excuse for not having the civilians, our allies, and diplomats out of the country before ceding control of the air base and airport to local authorities?
