Charles Lindbergh's Des Moines speech accusing the British, Jews and FDR's administration of conspiring for war with Germany.

Charles Augustus Lindbergh was an American aviator, military officer, and author. On May 20–21, 1927, he made the first nonstop flight from New York to Paris, a distance of 3,600 miles (5,800 km). His aircraft, the Spirit of St. Louis, was built to compete for the $25,000 Orteig Prize for the first flight between the two cities. Although not the first transatlantic flight which was in 1919 by Alcock and Brown who landed in Ireland, it was the furthest distance flown at the time by nearly 2,000 miles (3,200 km), the first solo transatlantic flight, and set a new flight distance world record. The achievement garnered Lindbergh worldwide fame and stands as one of the most consequential flights in history, signalling a new era of air transportation between parts of the globe.

The Des Moines speech, formally titled "Who Are the War Agitators?", was an isolationist and antisemitic speech that American aviator Charles Lindbergh delivered at a 1941 America First Committee rally held in Des Moines, Iowa. In the speech, Lindbergh argued that participation in World War II was not in the United States' interest, and he accused three groups of trying to push the country toward war: British people, who, he said, propagandized the United States; Jewish people, whom Lindbergh accused of exercising outsized influence and of controlling the news media; and the presidency of Franklin D. Roosevelt, who, he said, wanted to use a war to consolidate power. Called Lindbergh's "most controversial public speech", his use of antisemitic tropes and his monolithic characterization of American Jews as war-agitating outsiders prompted a nationwide backlash against him and America First that the organization "never recovered from".

Franklin Delano Roosevelt, also known as FDR, was the 32nd president of the United States from 1933 until his death in 1945. He is the longest-serving U.S. president, and the only one to have served more than two terms. His first two terms were centered on combating the Great Depression, while his third and fourth saw him shift his focus to America's involvement in World War II.
