The Obama administration on Wednesday slammed North Korea's pugnacious rants toward South Korea and the West and a U.S. intelligence official called the strident remarks worrisome.
"The ratcheting up of rhetoric is of concern to us," the official said.
The question is whether this is "just rhetoric," he said. Or, "are things happening behind the scenes indicating the blustering has something to it."
Another U.S. official said there is a lot of uncertainty about North Korea's intentions.

In a rare public appearance since admitting to an extramarital affair, David Petraeus apologized Tuesday night for the scandal that led to his resignation as head of the CIA last year.
Petraeus, a retired four-star general, has stayed out of the limelight since the affair was revealed in November.
"Please allow me to begin my remarks this evening by reiterating how deeply I regret and apologize for the circumstances that led to my resignation from the CIA and caused such pain for my family, friends and supporters," Petraeus told a crowd gathered at a Los Angeles hotel ballroom. "I am also keenly aware that the reason for my recent journey was my own doing."
His comments came at an annual University of Southern California dinner to honor the military. It was one of the fist major public appearance since the scandal derailed the illustrious career of the decorated Army general.
