This article is excerpted from Wall Street, Banks, and American Foreign Policy, chapter 8, "Rockefeller, Morgan, and War" (1984; 2011).
During the 1930s, the Rockefellers pushed hard for war against Japan, which they saw as competing with them vigorously for oil and rubber resources in Southeast Asia and as endangering the Rockefellers' cherished dreams of a mass "China market" for petroleum products. On the other hand, the Rockefellers took a noninterventionist position in Europe, where they had close financial ties with German firms such as I.G. Farben and Co., and very few close relations with Britain and France.
The Morgans, in contrast, as usual deeply committed to their financial ties with Britain and France, once again plumped early for war with Germany, while their interest in the Far East had become minimal. Indeed, US ambassador to Japan Joseph C. Grew, former Morgan partner, was one of the few officials in the Roosevelt administration genuinely interested in peace with Japan.
World War II might therefore be considered, from one point of view, as a coalition war: the Morgans got their war in Europe, the Rockefellers theirs in Asia. Such disgruntled Morgan men as Lewis W. Douglas and Dean G. Acheson (a protégé of Henry Stimson), who had left the early Roosevelt administration in disgust at its soft-money policies and economic nationalism, came happily roaring back into government service with the advent of World War II. Nelson A. Rockefeller, for his part, became head of Latin American activities during World War II, and thereby acquired his taste for government service.
