NTI Publishes New Paper: Connecting the Pillars of the NPT

A new NTI Paper, Connecting the Pillars of the NPT: Multilateral Disarmament Verification and Non-Proliferation, is a unique analytical contribution that explores the juxtaposition of disarmament obligations under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and verification challenges.

With 191 states parties, the NPT serves as the foundation for global efforts to curb the spread of nuclear weapons. A key pillar of the treaty is its commitment to disarmament, and it calls on all states—those with and without nuclear weapons—to contribute to the process. But the treaty leaves important questions unanswered: How can non-nuclear weapon states fulfill their obligation to contribute to disarmament if they are not allowed access to nuclear weapons and have no knowledge of their design, specific materials, or applied technologies? How can nuclear weapon and non-nuclear weapon states cooperate to verify disarmament while also protecting proliferation-sensitive information?

Authors Corey Hinderstein, NTI Vice President of International Fuel Cycle Strategies, and Lars van Dassen, Executive Director of the World Institute for Nuclear Security, address key questions and posit that non-proliferation and disarmament efforts can be reinforcing and not contradictory, especially regarding verification.

NTI President and CEO Christine Wormuth on the Expiration of the New START Treaty

New START, the last remaining arms control treaty capping U.S. and Russian nuclear arsenals, expires on February 5. This marks the beginning of a dangerous new era. For the first time in several decades, there will be no limits on nuclear weapons, less visibility into Russian nuclear weapons activities, and fewer tools to manage a crisis between the world’s two largest nuclear powers.
