It is pretty obvious that if given the option, Israel would drive every last Palestinian out of the Gaza strip just to be sure that Hamas can't send rockets ever again. Once Palestinians have left, they will never be allowed to go back. You end up with millions of stateless people. Also you pulled the last sentence out of your ass, talking as if Israel doesn't border the Gaza strip, because the city itself technically has no border with Israel.
