PESTERING PROVOKES WAR THREAT

Surely as a nuclear power North Korea could come up with something better than this:

"If the U.S. keeps pestering us and increases pressure, we will regard it as a declaration of war and will take a series of physical corresponding measures," the North's Foreign Ministry said in a statement carried by the official Korean Central News Agency. The statement didn't specify what those measures could be.

So, how are they going to retaliate... pester back?
