You can still be anti-semetic and fight Nazis. Hence the current Russian narrative of "judeo-globalism", "Soros", and extreme anti-LGBT sentiment.

Also I will say that you are not missing any context with those statements. Lukashenko is a known anti-semite in Belarus.

I think this is more complicated than a "enemy of my enemy is my friend" deal, Russia is finding an ally in Belarus because of their proximity to NATO. They don't exactly hold all the same ideological lines. That, and Russia isn't exactly fighting Nazism first, they're just fighting NATO encroachment and justifying it with the convenient fact that there happen to be Nazis in Ukraine to make the war sound good domestically and to make NATO look bad. Russia is just playing the self-preservation game like any other Capitalist country does.

Besides if they were actually against Nazism in every instance, they wouldn't be buddy buddy with Belarus.

So just to be clear, in the first quote, Lukashenko states that the Jews "made" the world remember the Holocaust, as if it wasn't something to remember in its own right, only something to be remembered after some kind of big Jewish campaign. A conspiracy, one might call it.
