You’re right, it’s not specifically Nazism. Japanese fascists and Italian fascists were not Nazis just because they were allies. They were their own brand of fascists. Israel likely does not approve of Ukraine’s nazism, but they also don’t care enough to condemn them unless Ukraine does something really stupid like defend Bandera’s role in the massacre of Jews, which has been done several times. They are all fascists who disagree with things that don’t really matter to their goals.
