the influence of the Arab nations is being dramatically exaggerated in this prose. No one controls the Pals except for Israel, the IDF army is boss, the rest of your prose hasn't been relevant for decades.
Egypt and Jordan "greedily" took the Gaza/WB areas? no. That was just how deeply their armies happened to penetrate in the 1948 years, also coincides where the Arab populations existed in majority at the time. Wasn't a "greedy" plan at all, with "no right to do so". Israel wasn't some kind of liberation hero for "kicking them out" in 1967. This sort of ideology is ultra right wing zionism where the Pals don't even have a right their own homes, bedrooms and bathrooms and only exist there due to good will of the Jews come came from all over the world from some magic time machine of 2000 years to claim what belongs to the glorious people. All Arabs should go back to Mecca.
Basically, this idea of the Pals as tools and pawns is very dated and no longer relevant. But if someone wants to live in 1981, so be it.
