Gaza and the West Bank should be Israel , they won a war that palestians and their allies started and when you start a war and lose the victor obviously gets some of your territory .
Are you in the 19th century? This is not how things are done anymore, for very obvious reasons.
except it was Palestine who started the War not Israel , if they never started a war of aggression Israel would never have had the territory they want back. Its simple they lost the war they started, so they have no reason to complain . In this case actually Israel = IF Kuwait beat Iraq, Palestine = Iraq (Agressors )
