Your take seems to hinge on holding an unfounded bayesian prior that israel is "the good guy" and therefore everything they do must be "defending". The world does not share this unfounded bayesian prior of yours, and thus remains unconvinced of the resulting conclusions drawn by israel and yourself. You will have to do a better job of convincing others, rather than simply asserting your opinions at them.
Without attacks from israel, there would be no response from Lebanon, Palestine, Iran, etc.
Israel also bombed southern Syria, to "protect the druze community". Syria has not attacked Israel, there are some random terrorist groups who did, but they attacked Israels' occupying forces in Syria.
Wake up: pretty much nobody believes the fascist, judeo-supremacist hordes of the current israeli government.
Are you sure you aren't in one of your own? Look to UNGA resolutions to see outside the bubble.

Netanyahu also added that having two strong rivals, this would lessen pressure on him to negotiate towards a Palestinian state..."
When was Palestine a liberal democracy?
