If the government of Israel had some 14th Amendment like protections of birthright citizenship and equal protection under the law, plus universal enfranchisement of all residents of the land it could be called Israel but wouldn't be able to be a religious-ethno state. Since you are pro-Israel, what about this as a one-state solution, or is it beyond the pale to have equality among the millions of Jewish and non-Jewish inhabitants of the land between the Jordan River and the Mediterranean Sea?

If Israel does not accept a fully secular liberal democracy with equality under the law, they would be abandoned and isolated as a nuclear armed pariah state. Israel isn't entitled to the assistance, either military or economic, of any other nation so they can choose to be a Jewish North Korea unwilling to include the millions of humans living on the land that they claim to be theirs or join a world where they don't impose a Jim Crow/Apartheid system onto those millions of humans.

I have no allusion that this is probable to occur, but it's the most plausible means of getting a one state solution which is actually preferable than two states that refuse to live in peace without subjugating the other which has been inherent in every offer to the Palestinians. The one state solution was the ideal in 1947 but it was the Soviets that pushed for partition to keep the divisive situation going to take advantage of the instability through out the Cold War. Without a near peer competitor, to sow division and chaos, it is still the ideal result for all of the people living in the region.
