I think the USA is unlikely to shift for as long as it's one single democratic nation, owing to internal political demographics. Same reasons it hasn't shifted on Cuba. But the USA keeps surprising me by failing to implode despite what all the politicians have been saying about each other, and by the anti-government language often used to justify gun ownership, so if I was in a position to influence Israel, I would be suggesting a diversification of international support.

But many times in history governments have done dumb thnings that backfired.
