According to Wikipedia, the U.S. became the world's biggest economy between 1865 and 1913, during which time nonfarm income grew 75%. The twentieth century became "The American Century" as the U.S. used its industrial and exporting might to purchase military superpower status and in turn used that to expand and maintain its global geopolitical influence, its non-empire empire that replaced the colonialism of the great Western European powers. In 2007, the economy of the EU passed that of the U.S. In 2010, the economy of China passed Japan's to become the world's second biggest. The Chinese are expected to pass the size of the U.S. economy by 2027. For nearly half a century, the U.S. competed militarily with the Soviet Union, a country with an economy that was never more than a small fraction of the U.S. economy. The Chinese economic miracle is not self-sufficient. It imports oil and coal to power its economic growth. It imports iron and copper and other commodities to create value added exports. It imports food to feed its massive population. Chinese government officials and businessmen are scurrying around the world, securing land in Africa for mining and agricultural operations, importing oil from Iran and south America and Saudi Arabia and Russia. The future is likely to be one of intense energy and commodity resource competition between the EU, China and the U.S. At what point, if ever, will China begin to use its military the way the U.S. has used it - essentially a long history of gunboat diplomacy and economics. The U.S. has no recent experience in competing for military superpower status with an economy larger than its own. How will future U.S. presidents respond to China's growing military and economic power?
