With the end of the First World War, American hegemony in the Western Hemisphere appeared to be an unquestioned fact of international life. The defeat of Germany, in combination with the wartime weakening of Great Britain and France, had created a situation whereby the major economic and political competitors of the United States were unable, at least in the short-run, to exercise the degree of influence they had enjoyed in the years before 1914. Given the strategic considerations involving the isthmian canal route, the circum-Caribbean region was the area within the Western Hemisphere where the influence of the United States was especially strong, a point born out by the existence of virtual American protectorates in Cuba, Haiti, the Dominican Republic, Panama, and Nicaragua. Accordingly, when viewed from an immediate post-World War I perspective, one might have anticipated that the United States would have had relatively little difficulty in maintaining a regional Pax Americana.
