This is a pretty balanced analysis about N. Korea.

Basically, we'll let the UN fumble around with it until either they nuke Japan, or they invade the south and we nuke them. Meanwhile, wait them out and hope for a collapse.
I feel really good that the UN is working behind the scenes with China, Japan, S. Korea, and the USA.
Korea is like what Iraq would have been in 15 years without Gulf 1.
Starvation is limiting their population growth, so they are going to run out of soldiers to man their army.
