Many are familiar with maps that outline all fifty U.S. states. And many are also familiar with the idea that the U.S. is an "empire," exercising power around the world. But what about the actual territories - the islands, atolls, and archipelagos - the country has governed and inhabited? In this book, the author tells the story of the United States outside of the United States. This book reveals forgotten episodes that cast American history in a new light. Readers travel to the Guano Islands, where prospectors collected one of the nineteenth century's most valuable commodities, and the Philippines, site of the most destructive event on U.S. soil. In Puerto Rico, the author shows how U.S. doctors conducted grisly experiments they would never have conducted on the mainland and charts the emergence of independence fighters who would shoot up the U.S. Congress. In the years after World War II, the author notes, the United States moved away from colonialism. Instead, it put innovations in electronics, transportation, and culture to use, devising a new sort of influence that did not require the control of colonies.--adapted from publisher's description.
