The vast majority of the world including the ICC and the UN does not consider Israel to be defending itself. By your own logic, Israelis are culpable for the genocide and land theft committed by their government.
I believe “vast manority” may be a stretch; do you happen to know if there’s a way to quantify that? In my bubble, almost everyone that I personally know and who generally has reasonable beliefs, is on the Israel’s side of this conflict.
