You make it sound like Israel have no cards to play. Russia, China and other states have made it clear that they are prepared to back Israel, even more so if that means an ally turning away from the US.
Of course Biden cannot hold Netanyahu’s feet to the fire, because otherwise it means withdrawing military support etcera. If Biden does this he will 100% lose electoral college votes and then we have trump in office.
I’m no fan of Netanyahu or current Israeli policy and if I could see a perfect solution where Hamas get evicted, Netanyahu gets thrown under a bus and unelected, to work towards a proper two state solution, I would happily support that… it just isn’t there and the Israeli lobby is stupidly powerful in American politics.
