I'm no military authority but, I could have told N. Korea we have nuclear subs within striking distance of N. Korea.

Our nuclear subs are capable to taking out the entire country. Our aircraft carriers were sent because we want them to see them.

You and the others like you will bitch when N. Korea hits Japan. or even the US with a missal. You are bitching because Trump is trying to prevent a SECOND Korean war.

Realize, Korea just needs to hit the land mass. We, insist upon EXPENSIVE, precise targets.

RE: nuclear bombs
LOOK UP WHAT A DIRTY BOMB IS. N.Korea and Iran among others can surely do that AND THEY ARE WELL AWARE OF IT-even if you are not.
