The territory added after that was a result of winning every war since then.
Not so. The Jewish National Home was, by treaty and through international law, to be established in the territory shown on the map provided. No territory has ever been added to those international boundaries (except Golan Heights). Those international boundaries have been confirmed since with other treaties, made with Egypt and Jordan.
There was territory removed from that which was intended to be the Jewish National Home, taken by the invading sovereign nations of Egypt and Jordan. That land was recovered in war and restored to proper legal sovereignty.
