North Korea seems to be doing an excellent job destroying itself without outside help. The death rate is hovering around an all-time high. Marxism is sufficent to destroy it even without war. The permanent famine due to the brilliant implementation of Marxist agricultural practice is going along at full force.

Now, if North Korea were to be stupid enough to attack South Korea, that would be its end, and the leaders of North Korea know it. The pathetic "Army" of North Korea has no chance whatsoever of winning a war against the South. The USA would not be needed at all.

North Korea will just implode like all Marxist states eventually do.
