You have been dispensing the same old crap and propaganda for so so very long, that you actually believe it to be true. Israelis actually purchased large tracts of land from the Palestinians or the people living there. Why would a body like the United Nations arbitrarily hand over land to a specific people without any regard for legitimacy unless it was valid??? Bottom line, the same way your Palestinians think they are entitled to the West Bank (Part of Jordan) and Gaza (part of Egypt), the Jews are entitled to Israel. Every document and religious movement recognizes that except for you Muslims. You don't recognize anything about Israel or the Jews in fact you would like them to dissappear all together. That is why Israel is so hesitant to return land because what they will get in return is a normalized "neighbour" armed to the teeth that will use terror as an excuse to attack, throw up their hands and say they can't control it or aren't responsible.
