Divining the future of European-American relations is particularly difficult when so many Western nations face contentious, rapidly changing domestic politics. In America, the one certainty is that there will be a new president on January 20, 2025, although we cannot confidently predict who. Since neither Donald Trump nor Kamala Harris have clear national security views, the prospect is for more confusion and disarray. Recent European elections have also produced inconclusive results, with more ahead. In such circumstances, taking a longer view of recent US-European relations may tell us more than speculating about transitory election results. A convenient starting point is the West’s victory in the Cold War. Today, few remember the Cold War theory of “convergence,” which held that communism and capitalism would gradually grow more alike, with peaceful relations emerging as socio-economic systems shed many differences. In short, pro-convergence advocates saw a world not too hot and not too cold, but just one large, happy social democracy.
