Well, it might be so but what's the point in Russia pissing off Finland while a good chunk of its forces is dedicated to the war in Ukraine? They're irrational but surely going "Let's start a war on TWO fronts!" is a step too far even for them?
The same goes for any other Nordic (and Baltic) countries.
The current Russian regime likes to demonstrate its power now and then, though, and to try and project its influence through intimidation. They can do that with their significantly smaller neighbours with no risk of military retaliation.
There are risks, of course, but those would be in the form of deteriorating relationships and the associated economical costs, or from losing overall international rapport and respect. Those don't seem to matter much to the current regime in Russia, though.
I also think its stupid to be a direct Russian neighbour and claim neutrality, but I don't connect that to how Finns are generally portrayed in Russia. (I hold that opinion just on general strategic and historical grounds.) In fact, I didn't even know Finns are generally portrayed some particular way in Russia.
So, how are Finns generally portrayed in Russia in your experience, and/or how is that realated to the stupidity of being neighbours with Russia and claiming neutrality?
