I think your ideas are quite flawed here. You're thinking like three parties sitting down at a table and talking, but that's not how this works. You're also making logic leaps without any evidence, which is just foolish.
Let's use Occam's Razor to see what's more likely here:
- Netanyahu is a piece of shit trying to cling to power and stalling to get one last show of force out the door to inspire his crazy ass base
- The US and Israel and all of their diplomats, representative bodies, and armed services scheming together in a room to keep this thing going with zero benefit to anybody but Netanyahu
I think most reasonable people would probably say it's the second choice. The you might say "Well, then the US should just stop supplying them", to which most would probably agree...except all the people who don't. So then you're pissing off the other side of the aisle.
It's a lose-lose for the US here for anything except a ceasefire. Suggesting otherwise makes zero sense whatsoever unless you have a deep seeded belief the US is out to get Palestinians for some reason, which would also be pretty insane, and I've seen no evidence of that either.
