Since the 1953, we all know that the Korean peninsula has become such a militarized area. And since China got nuclear weapons since its first successful test in 1964, any war in Korea would go nuclear. So the question is, when is the latest year another war on the Korean peninsula is possible without having it degenerate into a large-scale nuclear conflict (like a few nukes is ok but not on a massive scale)? And who would be the likely victor?
