Soviet block nukes are all in Russian Federation now, guarded above any imagination.
I'll be really unhappy if it will be Russia to use it first, but our military doctrine supposes using nuclear weapons first against an aggressor who threatens Russia or it's allies. "Allies" here means (as I think) united countries like Belorussia, as well as Ukraine and Kazakhstan.
