I don’t deny that. But I don’t think their military machine is as happy with the government as many would think. Plus, there is the fact that they’d be going to war with their Korean brothers...
If South Korean had the nuts, they’d start false transmissions on the army channels that Kim Jong Il was assassinated, China was guilty of it, and China is presently invading from the north. Then invade and see what happens.
Best defense is a great offense, go and eliminate the threat.
