Secretary Mattis testifies on global nuclear condition

Defense Secretary Jim Mattis says at a House Armed Services Committee hearing on defense strategy and nuclear posture review that a review of the global nuclear situation was suffering since Russia had reduced the number of its strategic forces agreed to in the New Start treaty, Russia had modernized weapons and other systems, advocating a theory of nuclear escalation as China expanded its nuclear forces to pursue new capabilities and modernize its conventional military to challenge American superiority. Mattis says North Korea threatens global peace and Iran remained a unresolved concern while nuclear terrorism remained a tangible threat.
