It's quite simple, really.
Israel just wants to exist. Palestine was never on the fucking map. Britain divvied it all up, and the Palestinians, with the help of some war-mongering Arabs, decided to whip 'em out and see who was bigger.
Israel won.
Today, they still want nothing short of everything (see Iran for reference), and Israel, being the badasses they are, are going to end it.
Good riddance to bad company..
