Biden is a committed zionist, and has been for his entire career. Yes, to a certain extent politicians are malleable. That does not mean they will automatically bend their personal beliefs to the will of the voters. You can see this in action right now, since most Democrat voters support conditioning aid to Israel and Biden refuses to do so.

More fundamentally, you need to reconsider the idea of voting for a politician and then expecting them to do what you want when they have made no indication that they will. At that point, you’ve lost significant leverage.

Who the hell are they supposed to vote for here? Both candidates have committed to continuing to help Israel commit genocide. The Dems refuse to do anything meaningful to motivate young people to vote, then complain that young people don’t vote and blame them for lost races. The Republicans sure as shit won’t do anything for young people regardless of the circumstances.

Notice that the schools, hospitals, residential blocks, etc in Lebanon are attacked without even a modicum of pretense. The justifications for bombing hospitals last year were clearly half-assed and false, but now they don’t even bother to give them.
