Abstract
This paper challenges the conventional wisdom that US power and preferences following World War II led to bilateralism in Asia and multilateralism in Western Europe. It argues that the challenges facing the United States in both regions were similar, as were US policies meant to address them. With some lag, the United States supported the economic recovery of the regional powers it had defeated (Germany and Japan), saw the restoration of regional trade as a prerequisite, sought military bases to assure postwar security, and envisioned rearming its former foes as part of its security strategy. The outcomes in the two regions reflected the preferences and reservations of regional actors. The critical differences between the regions were structural. The existence of middle powers was critical in Europe, the return of colonial powers to Asia precluded regional arrangements in the short term, and geostrategic differences shaped the requisites for regional security.
