The Israeli government is not National Socialist, which is what you seem to be saying. The Israeli goverment is not anti semitic either (and essential part of what the actual Nazis were about). The details matter here, as does the historical context.
Yes, the Israeli government is an appalling, genocidal, ethno nationalist regime with some fascist characteristics that is doing terrible terrible things against the Palestinian population. Doesn't make it Nazi or Neo Nazi though. However, it is situated somewhere in the wider fascist orbit.
But of course, you may think it sounds clever calling them Nazis. In reality, it makes you sound a bit of a dick (and open to suspicion of being an anti semite by implication).
So, best avoided then, eh.
