The Pentagon said Wednesday that the ICBM fired by North Korea was a first-of-its-kind missile that the U.S. had not seen before and represented a dangerous escalation of the threat posed by the regime of Kim Jong Un. "This act demonstrates that North Korea poses a threat to the United States and our allies, and we remain prepared to defend ourselves and our allies and to use the full range of our capabilities at our disposal against the growing threat from North Korea," said Navy Capt. Jeff Davis, a Pentagon spokesman.
