Sharp as a rusty cleaver. I really don't understand what you are trying to say. What about Vietnam? Who tried to conquer it, China? You understand what an annexation is? The only time an annexation worked since WW2 was sort of Tibet at least that I can remember.
That's just the thing: No one knows, not even the Russians.
Which is why they won't launch them. Cause that could lead to a worse outcome for Putin than total annihilation - public embarassment.
