N. Korea DOES have missiles -- they had a test failure, but that doesn't mean they don't have other long range missiles that may work.

North Korea has an untested ballistic missile capable of hitting the United States, top U.S. intelligence officials said Wednesday.
While testifying at a Senate committee hearing in Washington, CIA Director George Tenet was asked whether North Korea had a ballistic missile capable of reaching the U.S. West Coast.
Before answering, Tenet turned to very quickly consult with aides sitting behind him.
"I think the declassified answer, is yes, they can do that," Tenet said.

They are just talking on FoxNews about the US plane in the areat that can detect the nuclear detonation.
Their bomb is too big to fit on their missiles. It will be many years before they are able to miniaturize enough to put a nuke on a missile. Their only possible means of delivery at the moment is by boat or plane, either one of which is certain to be intercepted leaving their nuke and incontrovertible evidence in the hands of those they intended to attack.
