It would be detrimental because the big countries would take sides. I don't know how much China will support North Korea though.
While at base camp in the Nam circa 1969, I was watching Stars and Stripes tv concerning the South Korean people and their relationship with N. Koreans. The South Koreans are pretty much trained from early in life to expect another action from the north. The south can pretty much take care of itself in any case. They are a definite force to be challenged and I doubt if the north really wants any part of them. That being said, no treaty has ever been signed and there is an inbred (I only suspect) ego maniac at the helm so who knows what he'll do. With our own present administration I am not even sure what the reaction will be if Kim Jon Un decides to lob a missile into S. Korea proper or one of our allies, or possessions.
The stalemated war between the North and South keeps the North functioning. They use the current situation to maintain power and have no desire for an active war. The end will come, perhaps with te death of the current idiot king.
My question is, if there was another war between Korea, what would happen if the South won? Would the North be part of the South? Would there be a North and South anymore? And what would happen if the North won? Would the South live under the same laws and dictatorship? Could it spread to neighboring states? Sorry for all the questions.
Those are good questions, Gin0710. South Korea has, generally, favored reunification. Though I have read some of the younger generations are concerned about taking on the burden such in the manner than Germany did during reunification. Somewhat related, there is an interesting piece by ABC News about a hypothetical wear on the peninsula. Its entitled "Simulation: War on the Korean Peninsula" and may be read here.
It is pretty scary to think about. It almost seems like going to war with Korea would open a lot of other doors no one wants to open. With Russia on their power trip and the middle east in chaos, there's no telling what could happen.
It certainly could turn into a huge, horrible crisis there, but at the same time I wonder if those in North Korea who are not happy with their government and want to escape if they could would seize the opportunity to try to bring down the government or do whatever they can to cause change.
I think there is a lot bubbling on the surface. There is just a matter of time before it all bubbles over and the wars will start again. They never did sign a peace treaty, so there is nothing to stop them from starting again.
Actually North Korea wanted to sign a peace treaty on the condition of the US will never attack them again. The US government refused. So there is no treaty. Both sides have trained a lot of people for military actions expecting another war sometimes in the future. South Korea has an economy 10 (or maybe 20x I forgot) larger than North Korea. Thus the South have much better military equipment. South alone can take north without outside interference.
