Please stop with this nuclear nonsense. There's enough nuclear warheads in EU to make sure nothing is left of major Russian cities in case somebody got too bald. Dictators aren't suicidal maniacs, they're "just" maniacs.
That's true for the most part, but there are plenty of suicidal maniacs in this world, and it is partially luck that none of them have yet managed to become dictators of countries with nuclear arsenals. It's not a given.
