Reykjavík Summit (October 1986)

Participants and setting

The two principals were supported by negotiating teams from the United States and the Soviet Union. The informal, secluded venue in Reykjavík encouraged direct discussion and candid exchanges. The setting helped produce unusually frank proposals that moved beyond incremental arms control to consider dramatic reductions in nuclear arsenals and delivery systems.

Topics and points of contention

Primary topics included elimination of certain classes of nuclear weapons, verification measures, and the future of missile defenses. A central obstacle was the U.S. Strategic Defense Initiative (SDI), a research program for space- and ground-based missile defenses, which Soviet negotiators viewed as undermining the balance of deterrence. Negotiators made substantial progress on limits and verification, but disagreements over SDI and related verification language prevented a final agreement.

Outcome and legacy

Although the summit ended without a signed treaty, it achieved a breakthrough in mutual understanding and produced draft concepts that shaped later agreements. The momentum generated at Reykjavík contributed directly to the negotiation and signing of the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, which eliminated an entire class of missiles. Historians and diplomats often regard Reykjavík as a turning point that demonstrated how close superpowers could come to sweeping reductions.

Why it matters

Reykjavík is notable for the scale of the proposals discussed and for the candid atmosphere between two leaders whose dialogue helped de-escalate tensions. The summit illustrated both the limits of negotiation—where technical programs like SDI complicate political deals—and the capacity for summit diplomacy to create lasting change. The event is frequently cited in studies of arms control and Cold War diplomacy as evidence that bold proposals can shift trajectories even without an immediate treaty.
