The year 1986 was a very active and potentially significant one for arms control. Stockholm agreements were a limited but useful step toward regulating Warsaw Pact and NATO forces. The United States and the Soviet Union met at Reykjavik and worked out the basic elements of a series of potential agreements that had eluded them for many years. But the near-term prospects for concluding these agreements were not bright. Hard bargaining would be required to resolve important details not worked out at Reykjavik. The introduction of different U.S. and Soviet proposals for a second phase of strategic offensive weapon reductions sparked fruitless recriminations and produced a new area of disagreement. A large gap, probably not unbridgeable, remained on an agreement governing the development and testing of strategic ballistic missile defenses.
