An ethnocracy(etnostate) is a type of political structure featuring “rule by a particular ethnos in a multi-ethnic situation”. Israel is not ruled by single ethnos. Itamar Ben-Gvir -leader of party Otzma Yehudit with 6/120 Knesset members is Mizrahi Jews(arab jew). United Arab List have 5/120 Knesset members.

I once saw someone got accused for using dog whistle when they used the same comparison, but to Islamists and description of Amin al-Husseini relationship with Hittler.

Calling Israel and IDF nazi is a dog whistle to dehumanize them. They are not support Hitler’s ideology.
