This article addresses the role of small states in addressing security issues in Central Europe. Through an examination of the development of the Rapacki Plan, the authors trace the distinctive features of the national interests of small states in both Western and Eastern Europe. These interests were oriented towards the advancement of European integration, the resolution of the German question, and the mitigation of political and economic dependence on the USSR. Special attention is given to the Federal Republic of Germany’s (FRG) membership in NATO and the roles played by the United States, the United Kingdom, and other alliance members in attempts to address European security issues at the level of small states. Although the Rapacki Plan was never fully realized, its objectives were partially achieved. First, the arming of the FRG with American nuclear weapons and the deployment of American intermediate-range missiles on its territory were prevented; second, economic cooperation expanded, initiating the erosion of the “Iron Curtain”; third, a “universal idea of nuclear-free zones” emerged; and fourth, concrete steps were taken to prevent nuclear war.
