Defense Secretary, Nuclear Weapon | featured news

The Pentagon said Wednesday that it was sending a mobile missile defense system to Guam as a "precautionary move," as Defense Secretary Chuck Hagel said North Korea posed a "real and clear danger" to the U.S. military base on the western Pacific island, as well as to allies and other U.S. territory.

U.S. Defense Secretary Leon Panetta said on Sunday that Iran is only one year away from producing a nuclear weapon. In an interview on the CBS show "60 Minutes," Panetta said that “the consensus is that, if they decided to do it, it would probably take them about a year to be able to produce a bomb and then possibly another one to two years in order to put it on a deliverable vehicle of some sort in order to deliver that weapon.”
