The Bureau of Strategic and Eurasian Affairs is ACDA's center for nuclear arms control and disarmament with the nations of the former Soviet Union and with China. This includes:

  • implementation of existing strategic and theater nuclear arms control agreements (START I and INF Treaties);

  • implementation of the START II Treaty after it has entered into force;

  • negotiation and implementation of future nuclear arms control agreements;

  • implementation of the ABM Treaty;

  • negotiations concerning theater and strategic ballistic missile defense;

  • ensuring that nuclear weapons are being dismantled in an irreversible and transparent manner, and that the resulting fissile materials are safely and securely stored;

  • assessment of arms control aspects of the development of U.S. and NATO nuclear postures and policies;

  • exploration of arms control possibilities in the Eurasian region, including potential discussions with China on strategic stability;

  • assistance with conversion of former Soviet defense industry to civilian purpose; and

  • coordinating the U.S. Government's approach to issues that overlap the SSD and START regimes.


The Strategic Negotiations and Implementation Division is the ACDA center for arms control of long-range and intermediate- and shorter-range weapons delivery systems. This division supports and chairs the following U.S. Government interagency committees:

  • the policy formulation committee for the Joint Compliance and Inspection Commission (START I Treaty implementation);

  • the Special Verification Commission Support Group (INF Treaty implementation);

  • the policy formulation committee for the Bilateral Implementation Commission (START II Treaty implementation, upon its entry-into-force).

These committees have principal responsibility within the U.S. Government for developing instructions for the JCIC, SVC, and, eventually BIC delegations, and for diplomatic communications for delivery to the governments of the START I, START II, and INF Treaty Parties.

ACDA leadership of the negotiation and implementation of future strategic offensive arms reduction agreements, e.g., START III and deactivation commitment, will also reside in this division. Additionally, the Strategic Negotiations and Implementation Division assesses potential impacts on strategic arms control of new technological developments.


The Strategic Transition Division is the focal point within ACDA for the START III warhead regime, nuclear warhead dismantlement and transparency, strategic arms control dialogue with China, NATO nuclear arms control matters, non-strategic nuclear weapons issues and Eurasian regional arms control. The focus of much of SEA/ST's attention is on ensuring the control, dismantlement, and safe storage of nuclear warheads located in Russia, and on restructuring defense industries in the region. SEA/ST engages Chinese Government and non-governmental arms control experts on strategic arms control issues. SEA/ST studies possibilities for enhanced transparency and monitoring of nuclear warhead eliminations, and participates in negotiations on conversion of Russian weapons grade plutonium production reactors.

SEA/ST provides policy input, analytical and negotiating support to:

  • The development of the START III warhead regime;

  • Cooperative Threat Reduction negotiations for transparency at Mayak;

  • State-chaired Russian International Science and Technology Center, the Science and Technology Center of Ukraine, and the Department of Energy's Initiatives for Proliferation Prevention program;

  • Meetings of NATO's High Level group, Senior Defense Group on Proliferation, and Senior Politico-Military Group on Proliferation on nuclear policy issues;

  • Bilateral Defense Conversion Committee with Russia, Ukraine, Kazakhstan, and Belarus;

  • U.S.-China strategic arms control dialogue.


SEA/D provides analysis and support to the ACDA Director on all issues concerning ballistic missile defenses and the ABM Treaty. It develops, for Presidential approval, options for arms control policy, strategy, tactics, and instructions for negotiations in the Standing Consultative Commission (SCC). The SCC is the implementing body of the 1972 Anti-Ballistic Missile Treaty. SEA/D chairs the interagency SCC policy formulation committee in support of the negotiations. This division also prepares policy options on ABM and theater ballistic missile defense issues for consideration in other high-level U.S.-Russian bilateral discussions.

This division provides a senior member and at least one adviser to SCC negotiations, and to the five-year review conferences of the ABM Treaty. In addition, this division participates in discussions with other countries related to ballistic missile defense issues.

In addition, SEA/D is responsible for strategic space arms control matters, including space-based missile defenses and anti-satellite weapons. SEA/D provided analytical support to formulation of the National Space Policy released September 19, 1996, and the Global Positioning System Policy released March 28, 1996.
