Looks like it was a dud not a deception

From Breithbart:

The U.S. government has determined that one scientific test, among many conducted since North Korea's announced nuclear test, was consistent with a nuclear explosion, a senior administration official said Friday night.

The official, who spoke on condition of anonymity, cautioned that the administration has not made a definitive conclusion about the nature of the explosion.

"The betting is that this was an attempt at a nuclear test that failed," the official said. "We don't think they were trying to fake a nuclear test, but it may have been a nuclear fizzle _ an effort that failed." The official spoke on condition of anonymity because of the sensitive nature of the information.

If this is true I do not envy the scientists and engineers who caused little Kim to lose face before the world twice. They are likely on their way to a place with one entrance and one exit. The entrance is a gate and the exit is a chimney and what separates them is a great deal of screaming.
