If you see the problem between North Korean bullies and United Statesean bullies as a problem between North Korea and America, you may be a statist.
The North Korean bullies need to keep the North Korean prisoners from seeing them as the enemy (as they are), so they say they want to build nukes to protect their "country" from American aggression. But, it's not Americans who are the problem; it is the US government-- a totally different critter.
And the US government is an aggressive problem, not only to North Koreans, but to every individual on the planet. In the grand scheme of things, the US government is a much greater threat to someone living in a tiny town on the Great Plains than "North Korea" could ever manage to be.
However, this doesn't matter to the North Korean bullies, since it serves their need either way. Just as the boogyman of "North Korea" does for the US bullies trying to manipulate their prisoners into not storming the castle with torches and pitchforks.
Governments and their supporters are so pathetic. But they do play an effective game, as long as people don't think too much or too clearly.
