The problem of course is that the current course of action is self-defeating. It's inevitably radicalizing even more Palestinians -- hell, it's radicalized me -- and has made Israel, and to some degree the US itself, into an international pariah. The two-state solution, which is almost certainly the only real path to peace, is even deader now than it was a year ago, in part because Israel has been emboldened by its apparent impunity to work openly against it, and in part because of that radicalization in the Arab world. And in the process, the status of international law and order has been perhaps fatally weakened, and not in a way that even benefits the US.
So, while I get the "logic" behind it, the current US course ultimately seems a bit suicidal. It would take a cleverer person than me to figure out the mechanics of it, but I'd have thought the best way to undercut Iran, Hezbollah, and Hamas would be to strong arm all sides, but particularly Israel, to the table with the assistance and support of as many UN members and Western allies as possible (and I'd think this would be a generally pretty popular move), and more or less impose a two-state solution. Yes, I know -- the devil is in the details. But what they're doing now is patently not working.
As for this election, were I American I would likely be following the example of someone like Mehdi Hasan: fight like hell for change, but concede that, yes, one is inevitably going to have to vote for Harris, however distasteful the prospect might be.
