Unfortunately everything you said about israel is true, as an (expat) Israeli I see the current conflict only drives us further from any solution and more bloodshed in the future is almost certain.
Regarding Hamas, it’s a fundamentalist jihadistic group that will not stop until the complete annihilation of all the Jews, with that I’m certain as they are saying exactly that. However they can be overthrown, that is what this war is about. Who will replace them ? No idea. Might be even worse…
There are many good people on both ends that want to live in peace. Unfortunately the leadership is bad, driven by extremists and the politics are horrible (at least on Israel’s side, don’t know much about PA)
