Apparently you are historically illiterate.
The 'occupied' territories are lands taken by Israel in wars started by, and lost by their, aggressive Arab neighbors. If Syria, Egypt and Jordan had not attempted to wipe out Israel (as defined by the British Mandate 1923-48), they would still have all these lands. There is also no such country as Palestine, never was. That's the name of a region between Syria, Jordan and Egypt that was occupied only by Nomads up until shortly after WW2. Ask yourself why Syria, Jordan and Egypt don't want to give their people the citizenship they deserve? Even they don't want anything to do with 'Palestinians'.
