I really hope North Korea doesn't collapse before I'm able to visit there. That culture is an obsolete artifact of the darkest days of the 20th century. I find an archaic Orwellian society so heavy on brain washing and bullshit utterly fascinating.
And North Korea isn't scary because of North Korea. North Korea is scary because they're a puppet of China and any trigger in that area could start a World War scenario.
Wont happen.
An attack by NK is unlikely anyway no matter how much chest thumping they do as those in power have to understand it all but ensures they will die. The leader is one thing he can be crazy but the generals are another. They have to know that their lives would be forfeit in such an encounter of nations.
Also, the idea that China is going to get involved is simply off base. If WE attacked NK, that is a clar possibility but if NK is the aggressor it is another story altogether. China is not going to put their entire country in danger, go to war with their best customers and risk destruction on a global scale because of an errant and idiotic dictator of a small neighboring country. It is not in their interests to go to war with us anymore than it is in ours to go to war with China. An attack by NK will kill thousands of our troops. We are not going to fail to respond to that.
