Pentagon: North Korea 'Will Move Closer' To Reaching the U.S. With Nukes

Will it strap them to dolphins?

If North Korea continues with its controversial missile and nuclear tests, it "will move closer" to its objective of reaching the United States with nuclear weapons, according to a Pentagon report.

During recent heightened tensions on the Korean Peninsula, Pyongyang repeatedly threatened the possibility of nuclear attacks against the United States and South Korea, prompting questions on the progress of its weapons program.

North Korea's secretiveness has made it hard for Western intelligence agencies to gauge exactly what is going on inside its research facilities.

Many clues have come from the regime's large-scale tests such as the long-range rocket launch in December and the underground nuclear detonation in February.
