Assessing the application of the liberal consensus idea to postwar foreign policy, this chapter contends that myths about the bipartisan spirit of U.S. foreign policy have too long found ready acceptance from historians. Politics did not stop at the water’s edge, even when bipartisanship was at its supposed zenith during World War II and the early Cold War. While there was unanimity during the post-war era that the growth of international communism was a threat to U.S. interests, this did not mean that foreign policy was free of political conflict, and partisan charges that the government of the day was losing the Cold War were commonplace. Meanwhile, non-elite opinion evinced little support for confrontation with the main Communist powers, reluctance to engage in another land war like Korea, and concern about survival in the nuclear era. The divisiveness wrought by Vietnam was supposed to have brought an end to the “Cold War consensus,” but uncertainty over its meaning was evident well before this.
