Russia doesn't need their entire purported nuclear arsenal to lay waste the planet.
They maybe can't fight for shit. That much is apparent, but I don't doubt that they do have that club in the closet.
In Rachel Maddow's book, "Drift", she discusses the decrepit state of our own nuclear arsenal... and I don't doubt that Russia's are worse, but whatever the failure rate, I'd bet on a lot of them hitting somewhere near their marks.
You?
