>If Biden had launched this war, none of these people would have had a problem with it. I am 100% positive on that assumption.

I think you're wrong here. As a Biden stan who's gone to the mat debating Biden's policies here on HN many times in the past, he lost pretty much all of the remaining good will he had by defending and supporting Israel for so long after it became clear what they were doing in Gaza. Biden wouldn't be getting a free pass in the Middle East if it were helping Israel's goals (ignoring the fact that Biden is much more of a dove than Trump).
