I like how the US government invaded Iraq because they had a few ties to terrorists and maybe had weapons of mass destruction, but left North Korea alone. The same North Korea that brags about its weapons of mass destruction, announces to the world that it's trying to build nuclear weapons, is apparently proud of its title as a state sponsor of terrorism, and which is a more oppressive society than Iraq ever was (tracing all the way back to Sumer).
Way to go, government. Were you too afraid to invade a country that might have fought back?
