Seriously, what Israel is doing today is no different from what the Nazis did before and at the beginning of World War II, extreme nationalism, illegal expansion, annexation of foreign territory claiming it historically belongs to them, propaganda using the latest technology, terrorizing neighbors, military at the center of society.
They have the same intent, but there’s no proof that there is a plan to really actively murder all Palestinians. Also, people in Gaza now have about as much food to eat as inmates of Nazi concentration camps had in the first half of 1940’s, but the rest of the horrible torture is not being done.
So, basically, people are okay with what the Nazis did between 1932 and 1941. But from 1941 onwards, Nazis went over some line that is not acceptable.
In my opinion, Nazis were horribly evil already in 1932 and what they did back then was already absolutely condemnable, but it seems that most people in our society don’t share my view on this. You are allowed to commit a genocide using starvation and bullets, like the Nazis did until 1941, but when you start using actual gas chambers, it becomes a no-no.
The US has always shared NAZI ideology relative to the threat of Communism. That pre-1941 honeymoon period was due to shared ideology.
