There are really only two long term stable solutions to the problems of the Israelis and Palestinians, plus one more that's recognized internationally as a war crime.

Either Israel leaves the Occupied Territories and allows the Palestinians to create a state there, or Israel grants citizenship to the people in the OT. A two state solution, or a one state solution.

I could write thousands of words about the crimes and stupid decisions on both sides that have made implementing either choice more difficult, but that would change nothing. Both sides have spent over half a century trying to make life so miserable for the other that they leave. Neither side has succeeded, or will.

Israel, with its vastly superior military, controls the immediate options. Given their current behavior, there's no reason for the US to be supporting them.
