And why do you think it has not happened, yet? I think you know the reason! Eventually if they felt it was in their interest.......
You may well wonder why some politicians have said the best thing for peace in the middle east is......relocate Israel into the US. Bit extreme I would think. The phrase "wishing it on my worst enemy" springs to mind.
The Isralies are in their homeland. Why on earth should they be relocated anywhere but where they belong?
Why would Israel not wipe out those around them? Well, I have never heard Israel call for the annihilation of another nation. Perhaps their ethos is different from those around them?
You should go back and look at the original UN mandates for Palestine. Go back even farther and you have the Balfour Declaration. The Arabs created this problem, they use the "Palestinians" as tools to whip up stupid people, and they have no interest in solving the problem. If they had followed the mandate instead of attacking Israel and losing, everyone would have what they say they want.
Most of the so-called Palestinians have no historical claim to the area. Many are the descendants of terrorist kicked out of countries like Lebanon. Arafat, as an example, was from Egypt.
The people have been happy to be used and to put into power people who took what they could get and left the people in poverty in spite of the fact that billions have been donated to help them. Materials for building have been used for terrorist tunnels. Leaders have taken the cash instead of feeding the people. They use civilians as shields for their missile launch sites.
There is little to redeem at least the leadership, and perhaps the people since they do not have the sense to choose better.
On the other hand, Israel is a constitutional democracy and over 20% of their population are not Jews. Many are Arab Muslims. Citizens and legal residents all have the same rights and Muslims serve in their government.
