Why does this guy have to drag North Korea into this?

The US will never start an armed conflict with North Korea, because they do have one or more nuclear bombs for real, and when you push Kim with his back against the wall he might seriously consider using them, even on his own people if it means wiping out an invading force.
The risk is just to big.

Iran does not have a bomb yet, and we really should concentrate on taking the regime in Iran down because once they have a bomb the Middle East will be lost and it's hard to say what will happen next. Likely the world economy will collapse should Iran turn unto a nuclear regime.

So we should taken them out with everything we got, to ensure they do not get to a point where they can produce a bomb.
