Why is Israel an occupational force? That area of the world has changed hands many times over the last 3k+ years. Many countries around the world have been conquered and territories have been re-drawn in that period of time. We canāt roll it all back and if we did the Palestinians may not own all the land either. How do you think people would view the Palestinians still fighting for ātheirā land 1000 years from now?
In short, WWII changed the landscape in that area yet again and the Jewish people regained control of the old Kingdom of Israel they they lost by being conquered by the Assyrians.
