Here is a solution. Give the Palis Sinai. Then as a world body, the UN should turn it into a green country. Only sun, water and wind power. No pollutants, totall disarmed except for the police and basically every leftist idea piled into one grand experiment, down a no sodium diet.
Then move the UN there.
Here is the thing. If you gave Israel to tha Palis and moved every Israeli to Sinai, within 10 years Sinai would be a booming metropolis, Israel would be a $hi+hole and the Palis would once again complain.
