Event
The Project on Nuclear Issues (PONI), with the support of Northrop Grumman Corporation, hosted a half-day conference to discuss U.S. nuclear policy and strategy. The conference followed shortly after the release of the Trump administration’s Nuclear Posture Review (NPR) and featured panel discussions on capabilities and regional challenges featuring a range of perspectives, as well as keynote addresses from Under Secretary of Defense John C. Rood and Chairman of the House Armed Services Committee Mac Thornberry.
Overview of Keynote Speakers’ Remarks
In his opening remarks, Under Secretary Rood situated the 2018 NPR within the context of growing uncertainty in the international security environment characterized by adversary modernization programs and the increasing salience of nuclear weapons. He argued that the NPR reflected broad consistency with long-standing elements of nuclear policy while enhancing deterrence and assurance in a more challenging threat environment. Finally, he touched on the importance of developing a tailored set of capabilities to correct the potential for adversary miscalculations. Read the full transcript of his remarks.
In his address, US Rep. Mac Thornberry outlined three key points.
First, he referred to the U.S. nuclear deterrent as the cornerstone of national security. Thornberry stated that for seventy years the most existential threat to the United States has been a nuclear attack on the homeland. He emphasized the need for deterrence to prevent such an attack from occurring. However, he said deterrence is often neglected and its success is defined by never having to use the deterrent.
Second, he emphasized the need for continuous efforts. He emphasized modernization of weapons, delivery systems, and nuclear command and control to address the aging of the triad. He also said that it was important to consider changes in the international security environment.
Third, he praised the Nuclear Posture Review for leading the United States in the right direction.

Regarding clarity vs. ambiguity in declaratory policy:
Franklin Miller: “It is what it is, and it isn’t what it isn’t.”@ajmount: “If only it were that clear.”

.@KoriSchake: We’ve been too focused on preventing DPRK from acquiring nuclear weapons and not enough on denying the political value of those weapons – showing that it doesn’t change anything. #CSISLive

1. The U.S. nuclear deterrent remains the cornerstone of our national security efforts
2. A lot of work is needed to continue our efforts
3. This NPR moves us in the right direction#csislive— CSIS PONI (@csisponi) March 1, 2018
Our triad is aging and needs to be modernized. It’s not just the delivery system but the weapons themself and the nuclear command and control. Time takes its toll –@MacTXPress #csislive pic.twitter.com/rzGA98XcYz

Credibility is the most important when we talk about strategic deterrence. – @MacThornberry
— CSIS PONI (@csisponi) March 1, 2018
All three legs of the triad need to be modernized, at no point does it exceed 7% of our defense budget. I think we can afford that. – @MacTXPress
