There's certain things that we do work with Russia on and then there's certain things when they do something wrong, I have no problem calling them out on it.
North Korea's sin is that it refuses to surrender, to fall on its knees, to sacrifice its people. It refuses to become a slave. For centuries, European and later US colonialism punished such defiance in the most brutal ways. Western culture is, after all, based and built on slavery. It demands absolute compliance, unconditional submission. If North Korea is attacked, it should fight back! And it will.
