The U.S. has been spewing anti-Korea noises since the war stopped (not ended.)
   The only reason they have not invaded-like the other countries you mention-was because China would intervene, as they did before. Now, they might not. The production of nuclear weapons by North Korea is also a game-changer. Tough call, isn't it? For everyone's sake, let's hope our "leaders" don't start a war.
