It's not my job to solve a problem successive Israeli governments created by their decades of violations of international law. Maybe they can't find something they consider an "adequate reaction" that doesn't involve mass murder and ethnic cleansing. That doesn't make those legitimate, or moral, or legal. That is a problem of their own making.
Consider that if it was reasonable for Israel to murder many times more civilians in response to a Hamas attack on civilians, it would be equally reasonable for Palestinians to murder many times more Israeli civilians than that again in response to the IDF attack on Palestinian civilians.
But nobody have an inherent right to a reaction they consider fair, if that reaction involves brutally violating the rights of innocent third parties.
It's no less terror when the IDF kills innocent civilians than when Hamas does, and seeking to legitimise it is no less immoral.
