Why would anyone want to compromise against foreigners who illegally took over their lands? Its very simple, show me where the grandparents etc upto 3-4 generations ago of Israelis lived. And if they weren't in the geographical Israel did they come here peacefully or as a British project and later forcing the Brits to give up even more to these ingrates?
