Am I the only one thinking that this would be the perfect time to get China to drop this sorry excuse for a nation, and allow us with South Korea to invade them in a mainly SK operation with US support? This could be the chance to reunify the Koreas that the world has been looking for.
Reunification of the Koreas cannot be accomplished through a violent invasion. If that happened, then even if South Korea was successful in annexing North Korea, the North Koreans would likely resent them. Besides, there's a reason that neither Korea dares to invade the other. The DMZ(De-Militarized Zone, the 38th Parallel, the border between North and South Korea) is guarded by over 1,000,000 North Korean troops and as many South Korean troops. An invasion of North Korea would be extremely costly in terms of lives, and money, and would be an unwise decision. If it comes to an invasion of North Korea, I doubt that the United States would support South Korea regardless. The U.S. and South Korea are allies, yes, but China and North Korea are allies as well. And if the United States supported a hostile takeover of North Korea, then China would have more than ample grounds for a trade embargo with the United States, and we all know how much the United States relies on China economically. The United Nations will likely withdraw support from South Korea if they do invade North Korea, not only because China and Russia(allies of North Korea) are permanent members of the security council, but also because the United Nations tends not to side with the aggressor. If South Korea invades North Korea first, they're the bad guys. It is worth mentioning that the current secretary general of the United Nations, Ban Ki-Moon, is a South Korean, but even if he does support a South Korean hostile takeover of North Korea, chances are that his voice will be drowned out. Cut off from support, South Kora will have a very difficult time in such a conflict. Their economy, which is of course booming at the present, could take a severe hit, and they could be sent spiraling into an economic crisis. A South Korean invasion of North Korea would be a Pyrrhic victory at best, and would only result in further discontent and conflict as they attempted to corral the North Korean citizens.
If the two Koreas are ever going to be reunited, it must be accomplished through careful and patient politics. And who knows, maybe you're right, and this is the perfect opportunity. Perhaps Kim Jong-un is more open to the rest of the world than his late father.
I think I saw his name before, but...With the death of Kim Jong-il, Jang Song-thaek essentially has control of what happens next in North Korea, and I very much doubt that he is going to elevate Kim Jong-un to power. Song-thaek was and still is one of the most powerful and high-ranking officials in North Korea, and while the North Korean citizens might buy into the whole "Kim Jong-il is a god" thing, the higher ranking officials certainly will not. I foresee a military coup and further martial law in North Korea. Kim Jong-un, who is only a child after all, will probably be killed or imprisoned by officials vying for the seat of power who don't appreciate the competition. Even if he does manage to ascend to power, I doubt that he will be able to rule a nation competently as young as he is.
