A prime minister visiting Russia on victory day, sure sounds like pro-Russia to me.

I know plenty of Slovaks, and you can divide them into 2 groups:

First group are disgusted that their government is pro-Russia.

Second group claims the Ukrainian government was "bombing the Donbas", and finds it normal that "Russia went to defend the Russian speaking population".

But sure, the second group probably consider themselves "neutral" and not "pro-Russia". That doesn't mean we all have to consider them as neutral, since they are deep into the Russian disinfo.
