Agree on (1) and (2). I see no reason that the Knesset should be geographical based, I think the current system is fine.
Real peace with the Palestinians. Let them have Gaza and declare it a Palestinian State. It’s not like Israel wants it anyways. Come up with some sort of plan to give them the West Bank and Natzeret but keep Gush Etzion and Beitar. (We don’t need the rest. Set everyone up with cheap housing in the Negev.) Get the US to agree to send troops over to keep the peace for the at least next decade until all terrorists are dead or in jail and there has been no violence for three years. Put the Old City and surrounding area under UN control.
I have a weird degree of confidence in a Chareidi Knesset. Once there is no longer the need to have a “Jewish State” due to the unpopularity of religious and secular Zionism in the Knesset there should be less of a problem giving up settlements.
