War and Arms Control: Conditions and Strategies for Cooperation

Introduction: The Nuclear Shadow of the Ukraine War

• Russian Nuclear Rhetoric and Bullying: Since the invasion of Ukraine, Russian President Vladimir Putin has issued explicit nuclear threats to deter Western intervention.     * $24$ February $2022$: Putin warned that anyone who creates threats for Russia will face consequences "such as you have never seen in your entire history."     * $21$ September $2022$: Putin stated that if territorial integrity is threatened, he will "use all available means… this is not a bluff."     * $October$ $2022$: Senior Russian military leaders reportedly discussed "when and how Moscow might use a tactical nuclear weapon in Ukraine."
• Impact on Arms Control: This "nuclear bullying" has blurred the lines between conventional and nuclear domains and challenged the ability of arms control to constrain an authoritarian willing to use nuclear capability for coercive means.
• The Current Breakdown:     * $08$ August $2022$: Russia suspended inspections under the New Strategic Arms Reduction Treaty (New START), the last remaining bilateral US-Russia agreement.     * Geopolitical Environment: American and Russian negotiations currently seem "incongruous" due to Russia's efforts to change the international order.     * The Dilemma: While the environment is pessimistic, the United States and Russia have an obligation under the Nuclear Non-Proliferation Treaty (NPT) to pursue the "cessation of the arms race" and "general and complete disarmament."

Defining Objectives and Strategic Stability

• Post-War Theoretical Objectives of Arms Control:     * Improving security.     * Reducing economic costs.     * Preventing the "militarization of society."
• Definition of Strategic Stability: Arises when two adversaries possess:     * Survivable Second-Strike Nuclear Capability: The ability to retaliate even after an initial attack.     * Crisis Stability: Limited incentives to use nuclear weapons first in a conflict.     * Arms-Race Stability: Limited incentives to build up nuclear forces.
• The Complex Contemporary Environment: The Cold War dyadic (two-power) model is outdated. The modern landscape includes:     * Multifaceted competition beyond two states.     * Commingled conventional and nuclear capabilities.     * Capabilities vulnerable to detection, disruption, or disablement.

Historical Evolution of US Nuclear Posture Reviews (NPRs)

• $1994$ NPR (Clinton Administration): Established the role of nuclear weapons in US national-security strategy and led to a congressional mandate for reviews at the start of new presidential terms.
• $2002$ NPR (George W. Bush Administration):     * Post-$9/11$ focus on terrorists and peer competitors.     * Downplayed past agreements in favor of "maximum flexibility."     * Called for withdrawal from the Anti-Ballistic Missile (ABM) Treaty.     * Despite this, the United States and Russia negotiated the Strategic Offensive Reductions Treaty (SORT) in $2003$, cutting deployed strategic warheads over $10$ years.
• $2010$ NPR (Obama Administration):     * Reflected the "Prague Agenda" toward a "world without nuclear weapons."     * Prioritized preventing nuclear proliferation and nuclear terrorism.     * Focused on "reductions" (mentioned $61$ times) and New START.
• $2018$ NPR (Trump Administration):     * Noted that US efforts to reduce nuclear roles were not reciprocated by adversaries.     * Called out Russian non-compliance with the Intermediate-Range Nuclear Forces (INF) Treaty.     * Emphasized US flexibility, diversity, and resilience in capabilities to manage strategic competition.
• $2022$ NPR (Biden Administration):     * Depicts a volatile environment with the expansion of China's nuclear program and Russia's invasion of Ukraine.     * Notes that by the $2030s$, the US will face two major nuclear powers as strategic competitors for the first time.     * Endorses a "comprehensive and balanced approach" of deterrence combined with arms control, non-proliferation, and risk reduction.     * Signals an unofficial "arms-control hiatus" while remaining open to a New START replacement if Russia acts in good faith.

The Continuum of Conflict and Arms Control Windows

• Phase $1$: Peacetime (Geopolitical Cooperation):     * START (Signed $1991$): Limited nuclear warheads to $6,000$ and delivery systems to $1,600$ per party.     * Open Skies Treaty ($1992$/$2002$): Allowed short-notice observation overflights to collect data on military activities.     * Lisbon Protocol ($1992$): Committed Belarus, Kazakhstan, and Ukraine to transfer Soviet nuclear weapons to Russia and join the NPT as non-nuclear-weapons states.
• Phase $2$: The "Twilight Struggle" (Unpeace): Defined as competitions in the no-man's-land between peace and war where military risk is growing.     * NPT Negotiations ($1959$-$1968$): Initiated during a period of intense strategic competition to prevent the spread of nuclear weapons and promote peaceful energy use.     * SALT I and ABM Treaty ($1972$): Managed competition and helped consolidate detente despite ongoing rivalry.
• Phase $3$: Crisis and Post-Crisis Management:     * $1958$ Test Peak: USSR, UK, and US detonated more than $100$ devices in one year.     * Limited Test Ban Treaty ($1963$): Resulted from the fallout of the Cuban Missile Crisis; banned atmospheric, outer space, and underwater testing.     * The Hotline: Established as a result of the Cuban Missile Crisis to mitigate the risk of accidental war.     * Presidential Nuclear Initiatives ($1991$): George H.W. Bush and Mikhail Gorbachev unilaterally cut nuclear arsenals following the attempted coup in Moscow.
• Phase $4$: Post-War Resolution:     * Geneva Protocol (Post-WWI): Prohibited poisonous gases on the battlefield.     * Post-conflict negotiations in the Balkans, Northern Ireland, and Rwanda demonstrate arms control as part of wider peace settlements.

Strategies for the Arms-Control Hiatus

• Maintaining Existing Mechanisms: Continued implementation of New START and meeting via the Bilateral Consultative Commission (BCC).
• Ukrainian Conflict Termination Scenarios:     * If the conflict remains "frozen" (like Georgia or Moldova), Ukraine may focus on border strength over negotiation.     * If a settlement is reached, it could include limits on Russian tactical nuclear weapons in exchange for limits on US missile defenses in Europe.     * Future agreements with Russia will likely require limits on US missile defenses to be viable.
• Addressing China: The US seeks to draw China into arms control, potentially through a "human-in-the-loop" agreement for AI-driven nuclear decision-making among the UN Security Council permanent five (P$5$).
• Formal vs. Informal Approaches:     * Alexei Arbatov (Skeptic): Argues that informal dialogues are "merely scholastic exercises" and cannot replace the ceilings and verification methods of formal treaties (INF, START).     * Stephen Lovegrove (Pragmatist): Argues that because formal agreements are unlikely in the near term, focus must shift to "strategic risk reduction."
• Capacity Building:     * Arms Control Advancement Initiative: Proposed by NNSA Administrator Jill Hruby to advance warhead monitoring, verification technologies, and modeling.     * Deterrence IQ: Improving the conceptual understanding of deterrence, strategic stability, and adversary mindsets among US domestic stakeholders and allies.

Challenges to Future Cooperation

• US Domestic Politics: Any formal treaty requires the "advice and consent" of a heavily polarized US Senate.
• Trust and Compliance: Convincing stakeholders to support new agreements with Russia is difficult given its history of non-compliance.
• Revisionist Powers: Both Moscow and Beijing are actively working to change the established global nuclear order and have shown little regard for existing norms.
