It’s not at all intimidating, or unusual for a big power to regularly exercise their forces.
We do it all the time too.
Have they threatened Norway, Finland or Sweden directly?
You’re trying to make something out of nothing. The Russians are not a threat to Western Europe. They would be hard-pressed to get a division into Belarus against zero resistance.
They are a shell of a power. Except their nukes, which they would never use except in defense or retaliation. They are not in the suicide business.
No, Norway is not a “Crimea” but - the psychological preoccupation Russia has with these shows/antics is what’s irritating.
