Hmm. It is a weird conversation for me. Since I am not part of the conflict, as the outsider I believe I see some of the game played. Still, I do not want to spend too much energy on this since I am not sure I understand how you perceive things.
I think you are wrong, but you are wrong by equating Netanyahu and Israel. It is useful for the former. It would be hard to convince me it is useful for the latter. And then, even assuming tada part is uncontested ( not impossible in current configuration ), how exactly do you see this play out?
Yes I am serious. Obviously 1200 dead is sad. Disregarding the emotions, on an Israeli political level it IS useful to rally the country to finally handle the Palestine problem once and for all, which is what is happening right now.
I sincerely doubt it will be once and for all. It will only end once and for all when the Palestinians make a true effort to have peace based on 67 borders, and that's not happening any time soon.
Why kill one guy when you can kill all resistance and (future possible) resistance and tada you have a bunch of land and can expand your borders.
