Iowa serves as both a political audience and a point on a consequential route in the novel. In Des Moines, Lindbergh argues against U.S. entry into the European war; later, while flying to Louisville, he crosses Iowa on a trip whose destination carries the story toward a new political crisis.

Des Moines as a Political Setting

On September 11, 1941, Lindbergh delivers “Who Are the War Agitators?” at an America First Committee rally in Des Moines. The speech makes Iowa’s capital a platform for his case that the United States is being drawn toward war by interventionist forces, despite the absence of a feasible plan for victory. He presents the country as already involved in the conflict in many respects, while insisting that it is not too late to stay out.

An Appeal to Iowa’s Voters

The speech addresses the people of Iowa directly and casts them as participants in a national test of democratic and representative government. Lindbergh argues that public opposition can prevent war, urging listeners to organize meetings and write to their representatives in Washington. He identifies the House of Representatives and Senate as the remaining institutional means for Americans to make their will known. The appeal therefore joins a state-level audience to a larger argument about popular action and national independence.

A Later Route Across the State

On October 7, 1942, Lindbergh pilots the Spirit of St. Louis from Long Island toward Louisville, crossing Iowa on the way. He gives the White House only an hour’s notice before landing in Kentucky. The account places Iowa within the geography of the unfolding political emergency: the state that had hosted Lindbergh’s antiwar appeal is also crossed on the flight that brings him to a crowd in Louisville, after Walter Winchell’s assassination.

Narrative Significance

Iowa’s importance rests less on extended local description than on its two distinct roles in the political narrative. Des Moines is the site of a public argument over intervention, democracy, and the power of Congress; the later overflight makes the state part of the president’s movement through a country increasingly shaped by political conflict. Together, these references connect an earlier appeal to voters with the crisis that follows.
