Israel is slowly stealing whats left of Palestine. The cycle is essentially, Palestine launches an attack on Israel, Israel retaliates and bombs the shit out of Palestine, Palestine is left worse off than it started, because Israel just beat Palestine into submission it continues to push in and take more land.
This is not really a reason to support either, Palestine keeps giving the Jews justification to do it by attacking, kidnapping, and raping Israelis, and Israel keeps slowly taking over land in Palestine and kicking them out which is why the Palestinians mostly support Hamas despite him being a militant because they hate Israel for taking their land.
