The modern concept of globalism arose in the post-war debates of the 1940s in the United States. In their position of unprecedented power, US planners formulated policies to shape the kind of postwar world they wanted, which, in economic terms, meant a globe-spanning capitalist order centered exclusively upon the United States. This was the period when US global power was at its peak: the country was the greatest economic power the world had ever known, with the greatest military machine in human history. As George Kennan's Policy Planning Staff put it in February 1948: "have about 50% of the world's wealth but only 6.3% of its population. [… Our real task in the coming period is to devise a pattern of relationships which will permit us to maintain this position of disparity". America's allies and foes in Eurasia were still recovering from World War II at this time.
