Ballistic missiles are terrifying, but the truth is russia just doesn’t have very many of them. The use of the missile then is essentially an admission of bluffing since inevitably the best time to deploy this very production limited weapon is when russia maximally needs to project strength… which is when it is weakest.
I should have written working nukes. I might have missed some evidence, but if the world takes Russians by what they say… well, who forbids them to claim they have like a million of nukes? And blasters with lightsabers too. And a couple of dozens of death stars then.
