There are big cracks appearing in the US support of Israel. Apart from anything else it is a political calculation for Biden as many younger Americans in particular are very concerned with it.
48,000 voters in the Wisconsin Democratic Primary turned out in crappy cold weather to register their abstention as a protest against the Biden government's unstinting support for Israel. Wisconsin is a swing state with a population of 5.8 million, it was very close last time and will be important in the election, Michigan probably more so and it has a large middle eastern community.
The politics in the US are shifting and the major parties are going to have to react.
I reckon Biden will be looking for a cease fire in Gaza which he can claim credit for before November, and if that means manipulating a change of government in Israel then they will be quite willing to go down that road.
