It is somewhat an open question at this point - Russia's expansion efforts seem to be more focused towards the arctic at the moment, while undoubtedly over the last couple of years and ongoing future programs are making Russia (more) ready for war (more than just reactionary measures to NATO movements) that doesn't necessarily mean that war involving Russia in either imminent or inevitable or that Russia would be the aggressor but not something we can ignore either. (Its possible they would be emboldened to act with less consideration towards how we'd react and in ways increasingly more counter productive to us like Stolly said).
