It's unfortunately necessary to point out that a key component of the Nazi program was the erasure of Jews, as Jews.
To further enhance this point, neo-Nazis and skinheads, some of who exist within a chain of transmission from the original Nazis, retain this feature of planning to erase, expel or eliminate Jews as Jews.
Israel, being a Jewish state, cannot be Nazi. It will never be the "new Nazi" anything.
But, being a Jewish state, and defining that state in these ethno-religious terms, has set Israel from the beginning towards its present ethnonationalist condition, a condition further made precarious and unstable by efforts to reinforce its ethnonationalism with overt mythological and religious justification. The shorter term for this is palingenetic ultranationalism. The even shorter term for that is: fascism.
Adding in the increasingly aggressive and bloody-handed expansionism (or at times enclosure) - that is, the stealing of homes and the expulsion or killing of families, villages, tribes and finally peoples - that culminates in war crimes and at least reasonable claims of genocide, all justified in terms of safety for the core ethnic group, its ethnic continuity through time, and its primacy always over any remaining outgroups, it is or ought to be clear to all that Israel is a fascist state.
If Israel is a fascist state - and it seems undeniably so - than it does not belong to the community of republican democracies. And as with all fascist states, anywhere and at any time, it is the enemy of liberty, and must be treated accordingly, until those who lead it and those who profit from its operation are brought to justice and removed from the common good.
