U.S. intelligence official expresses concern about "ratcheting up of rhetoric"
The announcement follows a slew of recent threats from North Korea
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.
