“How to Hide an Empire: A History of the Greater United States.” That’s the title of a new book examining a part of the U.S. that is often overlooked: the nation’s overseas territories from Puerto Rico to Guam, former territories like the Philippines, and its hundreds of military bases scattered across the globe. We speak with the book’s author, Daniel Immerwahr, who writes, “At various times, the inhabitants of the U.S. Empire have been shot, shelled, starved, interned, dispossessed, tortured and experimented on. What they haven’t been, by and large, is seen.” Immerwahr is an associate professor of history at Northwestern University.
