There is broad, bipartisan support for the modernization of the nuclear triad, which includes bombers, intercontinental ballistic missiles, submarines and the systems that control them, a Defense Department expert said.
Robert Soofer, the deputy assistant secretary of defense for nuclear and missile defense policy, also said support is more divided for the creation of W76-2, which is a class of low-yield, tactical nuclear warhead that is different from those in the nuclear triad. An example would be a submarine-launched ballistic missile nuclear warhead.
To understand the divide over support for W76-2, one must have an understanding of the two schools of thought on the best approach to nuclear deterrence, Soofer told the Air Force Association Mitchell Institute’s Nuclear Deterrence Forum today.
Each school of thought has its advocates, including members of Congress, interest groups and think tanks, he noted.
The first school of thought is known as simple nuclear deterrence, sometimes referred to as minimum deterrence. The thought is that deterrence is best achieved with a limited number of nuclear weapons that, for example, could destroy a certain number of an adversary’s cities, Soofer said. The viability of the deterrence is created by an adversary’s fear of uncontrolled nuclear escalation.
