I don't know anything about Israel being involved with Nazis and Ukraine, but Israel absolutely profits from the existence of Nazis anywhere in the world. it gives them excuses to keep milking the Holocaust to get free victim bux from their allies.

Much like whether or not they're white, what they do or don't support is entirely a predatory calculation that varies from situation to situation. Given that they seem to believe that only they are capable of lying and the rest of the planet are just rubes for them to sucker, it's perfectly consistent.
