Israel & Palestine

Why can't they just get along? What is the problem with those Palestinians? What is the big deal with the existence of Israel? Israel, if I'm not mistaken, has accepted a peaceful Palestine, but the Palestinians and some of their fellow Arabs, seem unable to live in peace. Don't they get tired of the Israelis coming in an beating them up for awhile and then go home? If they would just recognize Israels right to exist and then stop launching missiles into Israel, there would be peace and that are could become something more than just a drain on the world.
