Modernization of Aging US Nuclear Arsenal Crucial for Deterrence

The United States' replacement and upgrade of aging nuclear weapons reflect a need to maintain the nation's deterrence posture, but the modernization push does not signal a renewed arms race, former deputy assistant defense secretary for nuclear and missile policy Brad Roberts told Sputnik.
Roberts served as US deputy assistant defense secretary for nuclear and missile defense policy from April 2009 to March 2013. In that role, he also served as policy director of the Obama administration’s Nuclear Posture Review.
