When it's getting to a point where far-right leaders appear to care more about the prosperity of Russia than their own nation or their allies... yeah it's probably misinformation. At best. At worst, it's targeted propaganda - lots of bots online!
It's better to have a balanced number of warheads so that this isn't possible.
For this reason the US and Russia always negotiated before reducing warhead numbers bilaterally. But the EU on its own is not in the same league.
Ukraine will all the backing of Europe is making no progress, if this was true, Russia would be expelled from Ukraine tomorrow, as it should be. Ukraine is an embarrassment for Europe, it strongly suggests that Europe is basically meaningless on the global stage.
And the most embarrassing of all is, Europe is still buying gas from Russia.
"suggests that Europe is basically meaningless on the global stage" ... it will take many years of deep military investment to provide a proper counter to Russian aggression. As of right now, Europe has been shown to be in a very weak and exposed position. This was obvious years ago, and should not be a surprise today. This is true of most of the NATO member states.
That said, simply because Ukraine is unable to expel Russia does not mean that it is a grand threat to Europe proper. Perhaps some eastern countries face some limited conflict, but I'm not convinced by this "domino theory" that Russia would engage in a WWII style invasion of Poland, Finland, etc.
