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.
