(this will never happen, God told the Jews “all of Israel” is theirs).
Israel’s main problem with Palestine is that it is full of Muslims who hate them. Even if a two state solution could be achieved, they still don’t want such neighbours.
So here is the plan… I researched all the religiously persecuted people in the world, and one that stands out are the Druze. They are not Muslim (it is hard to tell what they are…), and they are not fighters or haters. There are 1 million of them, mostly in Syria and Lebanon, with some also in Israel.
New Palestine can be a refuge country for the Druze, just like Israel was for the Jews. New Palestine would just be a portion of the Gaza Strip. The remainder of Palestine would become part of Israel.
Every Druze moves to New Palestine. 2-for-1, existing Palestinians move to Syria and Lebanon to live in peace with other Muslims.
Everyone then at least is living somewhere that they are not hated. Israel gets its “expansion” and no longer as enemies on that doorstep.
