The US wouldn't be capitulating right now if they were in a position to continue the war, and Israel can't do shit on its won. They will absolutely try to keep the war going, but they're running up against material limits here. I also doubt Trump himself really matters all that much here, there's a huge amount of political capture by Israel in the US, and this lobby is going to push for war no matter what. But US economy and military industry isn't capable of continuing it.
