The Atomic Bomb and the First Korean War

North Korea now has a hydrogen bomb.  Maybe.  Even if the bomb North Korea detonated on Sunday was not a hydrogen bomb, it was North Korea’s most powerful bomb yet. So far, President Donald Trump has not said (or tweeted) anything that comes close to the threat he made on August 8:  “North Korea best not make any more threats to the United States.  They will be met with fire and fury like the world has never seen.”
