Book excerpt: In The Problem of Asia, the celebrated American naval historian and strategist, Alfred Thayer Mahan, analyzes the geopolitical structure of world politics at the dawn of the twentieth century. Mahan wrote his book at a time when the United States was emerging as a world power, having recently acquired overseas territories as a result of its victory in the Spanish-American War. It was a call to America and its leaders to break with the intellectual tradition of Washingtons Farewell Address and to recognize that U.S. security was tied to the balance of power in Asia as well as Europe.
