North Korea Military Power: Video

Until a few years ago, the military power equation for North Korea was that if North Korea poured its million man army into South Korea, the joint US-South Korea military had to delay the conquest of the entire peninsula long enough for the American reinforcement from Japan.

North Korea's nuclear power change that calculation, whereby North Korea can now invade, point its nuclear missiles at Tokyo and the US bases in Japan, and tell the US military that if it tries to reinforce, Tokyo and the bases will be nuked. Given the choice of losing just South Korea or South Korea and Japan, the choice would be simple.
