Legal? Egypt invaded and then annexed Gaza which was seized FROM THE EGYPTIAN ARMY by Israel in 1967.
Again, these are BASIC FACTS that you are getting wrong.
From 1948-1967, Gaza was a part of Egypt along with the Sinai peninsula. In 1967, Israel invaded and occupied both. But Israel didn't annex it. Then in 1979 when Sadat and Begin made peace, Egypt discharged their ownership of Gaza.
At no point did the Palestinians ever control that strip.
Palestinians are the descendants of Arab Muslim colonizers who built a mosque on top of the holiest site in Judaism, in a city Mohammed never visited.
I even got you to admit that Jews were indigenous to Palestine BEFORE Israel was founded...another mistake of yours, this time inadvertent. You were trying to say the Jewish presence in the Southern Levant was small but what you actually ended up doing is confirming that Jews have had a presence there long before Israel and are therefore the true indigenous people.
