Israeli's try to legally annex any land that was not defined theirs at the time of declaring Sovereignty. There is a good reason why they haven't and why they forcefully attempt to retain it and take more. Because they have no other course and no legitimate right to it. A sane people would withdraw and be grateful for that land they were gifted at the end of the War in 1948. Look at all the energy and time and money they have wasted to arrive at being the most disliked people globally for all their misguided efforts.
