Israel is objectively in the right. The only perspective where they are not is if you are an Islamic fascist who believes God wrote the quaran to Mohammed and hamas has interpreted it correctly to say the entire world should be compelled to be a Muslim theocracy.
Every war results in civilian deaths, WW2, the civil war etc… Hamas hides behind civilians , in the history of the world there is not a nation which has taken more steps to avoid civilian casualties of its enemies than Israel
