Overview
This lecture covers the modernization of the U.S. nuclear deterrent, the upcoming Nuclear Posture Review, current global nuclear threats, and the role of arms control and verification, followed by a Q&A addressing prospects for arms control negotiations and verification improvements.
Background and Speaker Introduction
- Guy Roberts served as Assistant Secretary of Defense for Nuclear, Chemical, and Biological Defense Programs (2017–2019).
- Roberts has extensive military, legal, and policy experience, including high-level roles at NATO and the U.S. Department of Defense.
- The lecture centers on U.S. nuclear policy modernization and the Nuclear Posture Review.
U.S. Nuclear Deterrence and Modernization
- Each new U.S. administration reviews and updates nuclear policy (Nuclear Posture Review).
- Deterrence aims to prevent aggression by posing unacceptable risks to potential adversaries.
- Russia, China, and North Korea are expanding and modernizing their nuclear arsenals.
- Modernization of U.S. nuclear forces is seen as essential due to adversary buildups and aging systems.
- U.S. nuclear forces consist of a triad: land-based missiles, submarines, and bombers.
- Modernization includes new submarines (Columbia-class), bombers (B-21), missiles, cruise missiles, and command and control systems.
Rationale for Deterrence
- Nuclear deterrence has prevented great power wars since 1945.
- The threat posed by nuclear weapons deters large-scale conflict and preserves peace.
- U.S. nuclear weapons are viewed as a political tool to maintain stability and reassure allies.
- Calls for unilateral disarmament lack evidence of reciprocal restraint from adversaries.
Global Nuclear Threats and Arms Control
- Russia is increasing its reliance on nuclear weapons, building systems outside current treaties.
- Russia has violated multiple arms control agreements (e.g., INF, Open Skies, Biological Weapons Convention).
- China is rapidly building its nuclear arsenal without treaty constraints and refuses arms control dialogue.
- Genuine arms control requires robust verification; without it, agreements are ineffective.
Cost and Criticism of Modernization
- Modernization is projected to cost 3.7% of the Department of Defense budget, historically low for nuclear spending.
- Critics claim modernization is too expensive or will spark an arms race, but adversaries’ buildup continues regardless of U.S. actions.
- Maintaining the triad enhances deterrence; reducing to a dyad increases vulnerability.
Nuclear Policy Predictions and Future Directions
- The upcoming Nuclear Posture Review is expected to maintain the triad, reject "no first use" policy, and continue modernization.
- There will be effort toward multilateral arms control, though progress is unlikely in the near term.
Q&A Highlights
- Affirming that "a nuclear war cannot be won and must never be fought" is seen as positive for U.S.–Russia relations.
- Verification expertise (e.g., Sandia Labs) is critical and should be reinvigorated for new arms control agreements.
- Skepticism remains about near-term arms control progress due to compliance issues, especially with Russia.
Key Terms & Definitions
- Nuclear Deterrence — Using the threat of nuclear retaliation to prevent aggression.

- Strategic Stability — Condition where adversaries are deterred from launching a nuclear attack.
- Arms Control — International agreements to limit or reduce weapons and enhance security.
- Verification — Measures to ensure treaty compliance through inspections, monitoring, or other means.
- No First Use — Policy commitment not to use nuclear weapons unless first attacked by nuclear weapons.
