The complete story of American imperialism is missing from our history books. On this week’s On the Media, how the United States worked to capture territory and expand power, while preaching democracy and freedom. [01:00] Host Brooke Gladstone sits down with historian Daniel Immerwahr, on the hidden history of the United States empire. For Americans, empire often means economic and military power abroad, or CIA coups in Central America–not British-style imperialism. But the American empire was — and in some ways continues to be — a lot closer than most people realize. Immerwahr explains the role of guano — bird poop — in launching America's overseas empire, and the legal, political and social clashes that ensued.[17:57] Host Brooke Gladstone continues her conversation with historian Daniel Immerwahr, exploring why, at the dawn of the last century, the arguments over imperialism didn’t end with poets like Rudyard Kipling and writers like Mark Twain. How should the adolescent U.S., big-headed about its democratic values, grapple with capturing territory? Immerwahr explains how this vital debate blazed across America’s consciousness like a comet, then vanished just as quickly.[34:47] Host Brooke Gladstone and historian Daniel Immerwahr conclude their conversation, discussing how, after World War II, global anti-colonial sentiment (combined with less dependence on natural resources) led to a shrinking of America's physical empire. But the American empire didn't disappear — it merely changed form. This originally aired in our April 5, 2019 program, “Empire State of Mind.”Further reading/listening/watching:How To Hide An Empire: A History of the Greater United States, by Daniel Immerwahr On the Media is supported by listeners like you.
