Norks' sub launched missile a serious threat

Washington Examiner:

North Korea's test of a submarine-launched ballistic missile over the weekend was at least a partial success, a Pentagon official with access to U.S. intelligence tells the Washington Examiner.

"This is something that started as a joke, but has turned into something very serious," said the official, who spoke on condition of anonymity because he is not authorized to discuss the initial U.S. assessment publicly.

North Korea has been working feverishly to try to develop the capability to launch missiles from submarines, and claimed success last year, releasing photos and videos that the U.S. quickly concluded had been faked.

This time though, the Pentagon believes the launch from the North Korean submarine "Gorae" was a success. The actual flight of the KN-11 missile, however, was a failure, in that it traveled a short distance, around 20 miles.

The Norks want to threaten the US West Coast and eventually the whole country.  It appears the Obama administration is not willing to do much to stop them at this point.  No drama Obama has not indicated what his response if any will be.
