In 1915, the United States experienced the 9/11 of its time. A German torpedo sank the Lusitania killing nearly 2,000 innocent passengers. The ensuing hysteria helped draw the United States into World War I-the bitter, brutal conflict that became known as the Great War and the War to End All Wars. But as U.S. troops fought to make the world safe for democracy abroad, our own government eroded freedoms at home, especially for German-Americans. Free speech was no longer an operating principle of American democracy. Award-winning author Ann Bausum asks, just where do Americans draw the line of justice in times of war? Drawing thought-provoking parallels with President Wilson's government and other wartime administrations, from FDR to George W. Bush, Bausum's analysis has plenty of history lessons for the world today. Her exhaustive research turns up astonishing first-person stories and rare images, and the full-color design is fresh and stunning. The result is a gripping book that is well-positioned for the run-up to the World War I centennial. National Geographic supports K-12 educators with ELA Common Core Resources.
