The 600,000 deaths are what are called civilian casualties, and we both know good and well that Hamas is responsible for those casualties. And no Israel isn't trying to do the same as the Nazis, that's some classic jihad cherry-picking. And if we go by your logic, then the allied power were more like the Nazis during WW2 as a lot of German civilians died. And to answer your second question, your trying to imply that the Israelis are learning the Nazi war methods, which 1, blitzkrieg while yes invented by Nazis, however is used by multiple world powers, but the fact that you only point at Israel doing it is absolutely baffling. You clearly need more learning my friend.
Their are very little of what you call "Israeli Nazis." In fact they no longer exist, and why would Pro Palestinians support "Israeli nazis" when they already chant nazi slurs to innocent Israelis? Riddle me that. However their are more Palestinians that are more sympathetic and supportive of the nazis than Israelis.
