No, it's communist. It's just called Juche. Note that nothing about how things are actually done in NK changed when they changed their constitution. Note also that constitutions are essentially meaningless in a dictatorship, since they provide few, if any, real constraints on the dictator. Which, after all, is why we call them dictators.

Looks like the fall of most of the communist states has gotten the regime a bit nervous. Can't have any of the little people thinking they might like to end their Socialist Paradise.
