Should Japan and South Korea have nuclear weapons like Donald trump says and he says we should leave NATO is he right
No, they would have sanctions imposed on them.
Look at North Korea and Iran. Both got sanctions because of their nuclear weapons programs. North Korea continues to do so.
I can't tell if you are serious or not.
If you are, 1 it would cause countless civilian deaths, 2 Would make China extremely unhappy (possibly even war) 3 Again War. 4 extreme backslash from the rest of the world.
Nuking them should be the furthest thing from your mind.
Kim Jong UN sees that China is tired of North Koreas actions.
Then someone just takes Kim's place. Anyway a collapse of North Korea would cause millions of refugees and a lot of money trying to reunite the two Koreas.
The language is not exactly the same. They have evolved over time and North Korean defectors have trouble understanding things in South Korean schools. The infrastructure in North Korea is awful compared to the South. Which will cost a lot to modernize. The people have been brainwashed. It is not as simple as speaking the same language. There are many reasons why a collapse of North Korea would be a crisis. It would not even come close to German re unification.
North Korea is already very weak.
