Chechnya, Georgia...if you were thinking you had a chance, now would be it.
The nuclear threat is always there but the Russian Federation is a decrepit power. The nuclear weapons are useless for power projection without having a conventional threat to go along with them. For countries that are in the near Russian sphere, Russia's bark is far louder than their bite has proven to be.
There is a huge swath of territory that just opened up across Central Asia that is going to be up for grabs for influence between the two largest poles of the multipolar world that is opening. China is trying to get in with the Belt and Road Initiative. Russia's influence looks like it should be waning as it will not have the military reach to effectively project true power. The NATO/Western aligned pole should be working on a similar plan to pull those resource rich areas into their sphere. In the process, the Russians are going to be more pinned in than they already are. Either by more Western friendly nations or by the new Asian Hegemon in China.
Even with nuclear weapons, the Russians don't matter much anymore.
