Israel is quite the difficult question here.
For one, I have to admire much of their policies and their tenacity to fight for a piece of the world to call their own.
At the same time, you also realize that they indeed stole the majority of that land. Jews plunged the world into a second great war for a piece of inhospitable desert, and to this day they continue to harness the warmachine of America to sustain and even expand their borders.
Should World "jewry" (as in zionist, global elites) be disbanded and the Israeli people be granted a new state, then surely there is no reason for them not to stay in their land.
However, the Palestinians need a land of their own and the new State of Israel should commit themselves to relocating the Palestinians.
