I have a revolutionary idea. Why don't we just expel EVERYONE from that part of the world, build a massive wall around it (already started, nice), flood it, and tutrn it into an underwater holy theme park?

Because the country that tries to do that will be met with massive military force from Israel.

The Israelis and the Palestinians can decide if their lives are more important than their land, and leave or stay.

Israel has enough nukes to destroy any country that invades it with the intention of expelling them.

The country that invades can decide if expelling the Jews is more important to them than continuing to exist.

Oh, I'm suggesting it be done by the world at large.

Well, not every country might be destroyed immediately, but the ensuing nuclear fallout would ensure that they all paid a horrible price in the long run, if things went badly.

It's really not feasible or realistic. Far too big a cost to solve a fairly minor conflict in the big scheme of things.
