You are too high on drugs. If they are not the " world power " pretty much in Military because of the Nukes. You would have , with NATO invaded and bomb them like Yugoslavia in the 90s, because of their incursion into Ukraine.
Stop Coping and be realistic.
Nukes are a great defensive deterrent, but their usefulness as an offensive weapon or tool for power projection is extremely limited. And like you've said: in a conventional war, NATO could steamroll Russia with ease.
Russia's ability to project meaningful amounts of military power is pretty much limited to its own periphery. Messing around with mercenaries in failed African states doesn't change that.
And when it comes to the economic and cultural sphere, Russia's influence is just too small to qualify as a world power.
The world is moving toward a more multipolar order, with only the US and China being superpowers with global weight. The EU, India, Russia and Brazil will be the secondary powers, Saudi Arabia, Japan and Australia the tertiary ones.
