North Korea may have nuclear missile

(CNN) -- A study just completed by the U.S. Defense Intelligence Agency says North Korea may have nuclear weapons that could be delivered by ballistic missiles, a congressman said Thursday.

The revelation came from Rep. Doug Lamborn, R-Colo., during a House Armed Services Committee hearing.

"Quoting from the unclassified portion, which I believe has not yet been made public, they say, quote, 'DIA assesses with moderate confidence the North currently has nuclear weapons capable of delivering by ballistic missiles. However, the reliability will be low,'" Lamborn told Joint Chiefs Chairman Gen. Martin E. Dempsey, who was testifying before the committee.

Lamborn asked Dempsey whether he agreed with the assessment. Dempsey appeared to be caught off-guard.

"Well, I haven't seen it," Dempsey replied. "And you said it's not publicly released, so I -- I choose not to comment on it."

U.N. Secretary-General Ban Ki-moon later told CNN's Wolf Blitzer, "We do not have any independent information to verify" the DIA study's assessment.

Is North Korea serious about military action? Or is it just testing the world?
