Ideas do not float freely: transnational coalitions, domestic structures, and the end of the cold war

Realist or liberal explanations for the end of the cold war cannot account for the specific content of the change in Soviet foreign policy or for Western responses to it. These theories need to be complemented by approaches that emphasize the interaction between international and domestic factors and that take seriously the proposition that ideas intervene between structural conditions and actors' interests. Some of the strategic prescriptions that informed the reconceptualization of Soviet security interests originated in the Western liberal internationalist community, which formed transnational networks with “new thinkers” in the former Soviet Union. These new ideas became causally consequential for the turnaround in Soviet foreign policy and also had an impact on American and German reactions to it. Even though transnational networks were active in Germany, the Soviet Union, and the United States, their success varied. Domestic structures like the nature of political institutions, state-society relations, and political culture determine the ability of transnational networks first, to gain access to a country's political system and second, to build “winning coalitions.” These differences in domestic structures can largely explain the variation in impact of the strategic prescriptions among the three countries.
