Joe Biden has called himself a Zionist. He will always support the state of Israel. But that doesn't mean he doesn't care about the Palestinians on ethical and moral grounds. It's pretty clear to me the thinking has shifted since October 7th, but the Biden administration is not ready to disavow the current government of Israel. If that's even possible, it would take a lot.I mean, the central point is pretty hard to argue against. Neither Biden nor Trump will stop what's happening, not on their own.
Biden isn't doing much. He's fucked, at least partly (maybe?) because he needs jewish votes. Partly because he's old school and probably really does "like" Israel, no idea. The reality is, he's not doing much.
That said, however little Biden is doing, Trump will probably do less. Trump really doesn't want to be involved in foreign stuff unless it's about him. Once he's elected, he won't give two shits about the entire area--right now he's soaking up the Evangelical vote and he knows they worship Israel.
If he does or says anything after getting elected, it will be to aid Israel in what they are doing beyond what we currently are giving them. In no possible world would Trump be favorable to the Gazans. Trump has already said basically that Israel should "get it done with" which means, go in there and flatten Gaza and exterminate the roaches. So yeah, young people upset over Gaza and voting Trump (or not voting and helping Trump in that way) are in for a bit of a shock IMO.
You keep bringing up the Jewish vote, but they are a tiny part of the electorate. And probably mostly living in cities in blue states anyway, so it's not the vote that he needs. But rather the political influence of Jewish-Americans (the campaign just raised $30M in Hollywood the other night).
While it's fair to assess that Biden isn't doing "enough," it's unfair to say he's doing nothing and it's patently absurd to say there's no distance between Biden and Trump on Israel/Palestine policy.
If you look at the major foreign crises of the Biden administration critically, one theme you might see is that they've been slow and reactive time and again. In AF, they waited until the Taliban was about to topple the capital before ordering a military evac. Our support for UA has been unwavering, but it's always been slowly reactive to the real-time needs of the conflict. IIRC Zelensky said that they could've used F16s over a year ago, when it wasn't on the table. In Gaza, we have little to no say in the IDF's revenge campaign. But as the humanitarian disaster has unfolded, we first air-dropped aid and then built a $300M pier that broke in the first storm. Again, sluggish when Bibi continues to treat the U.S. as the junior member of our alliance.
(I'm not privy to internal debates within the administration, but my gut feeling is that NSA Jake Sullivan is terrible at his job.)
