Yes. We did. And yet again it was the Democrats. For all his flaws, Nixon was actually doing a decent job in Vietnam. But then the Democrats started whining and so we pulled out of Vietnam, abandoning it.
I also agree. That was a poor leadership decision.
You see, your argument is "this happened before, so it's not Biden's fault!" Besides being somewhat of a red herring, this fails to recognize that Biden was the leader of the United States during this botched withdrawal from Afghanistan, and so he thus shoulders the responsibility for the failure of said withdrawal. Or at least, he should. People like you will continue to cover for him.
