"If you look back over our history, it will not take you long to realize that our people have shed more blood for other people's liberty than any other combination of nations in the history of the world." -- Fred Thompson, stump speech in Iowa, September 6, 2007.
Fact Check: While heavy, U.S. military casualties are still relatively low in comparison to the military casualties of its World War II and World War I allies. In World War II alone, the Soviet Union suffered at least eight million military deaths, or ten times the number of U.S. deaths in all wars combined.
