We could argue all day about what Russias doctrine is, but I would argue Russias doctrine at this point is irrelevent, it’s all upto Putin on wether or not he’d give the order and I doubt he would feel restrained by doctrine or tradition.
While I agree that it would be better for my theory not to be testes, per murphys law, someday it will be. My bet is that when Russia disintegrates (when, not if) we’ll find out the new states don’t have any workable nuclear weapons to divvy up.
And that makes sense. Because of three facts.
1) maintenance of nuclear weapons is bloody expensive
2) russia is the poster boy for corruption
3) should the corruption ever be found out, it would have been the end of the world anyway
