At the start of World War I, America was ranked twenty fifth in the international list of military powers. After two world wars fought by Europens chiefly for heir nation state rather than politicl convictions; Europe lay devastated and despoiled. The question of who would control the region was decided; economic power was assumed by Germany, and political power by France or nearby francophone countries. The old superpowers were bankrupted; and America inherited their role; but now faced new competitors -- with Japan and China in the lead.
In the Pax Britanica of the eighteenth century, Britain was known as the "Policeman of the World," a role now devolved to the U.S. World influence requires blood and money to back it up, and the will to lead. It is America's time to pay for its place in the sun, or step aside. Let us watch with interest.
