I’m not sure it is reasonable to “defend” either side at this point. There are radical and moderate, innocent and guilty, peaceful and violent, reasonable and unreasonable people in both Palestine and Israel, and peace proposals have been made and rejected many times. I doubt many people outside of the situation have unlimited support for either side since both sides have committed atrocities.
I would guess that most observers realize that decades of alternating peace and war in Israel have shown that no lasting peace is possible until one side leaves.
After watching this conflict for 40 years, I have empathy fatigue. I don’t really care who wins anymore, but this region has been a powder keg for too long. I also don’t care whose “fault” it is anymore. All parties have to leave that behind and get to practical solutions. 75 years of unresolved active conflict is just too long.
Israel is too powerful. It will not be moved or defeated, and another all-out war by another coalition of Arab states will hurt the Palestinians as much as the Israelis. Nor will Israel ever allow the “right-of-return” of millions of Palestinians to Israel proper because then the Jews would be demographically overwhelmed. Therefore, the most practical, peaceful and humane, if not the most just or fair, solution is for most Palestinians to be properly re-settled outside of Israel, far from the Israeli border, where they can start new lives.
