Lindbergh was an outspoken leader of the America First committee of isolationists and accused Roosevelt and American Jews of being agitators for war. He also made frequent trips to Nazi Germany and was criticized in American media for his antisemitic remarks and his praise of the Nazi regime, including his description of Adolf Hitler as “the world’s greatest safeguard against the spread of communism and its evils." Anne Morrow Lindbergh: The wife of Charles Lindbergh who in the novel brings an end to the civil unrest and political crackdown brought about by her husband's disappearance with an appeal to her countrymen via radio address. The real-world kidnapping and murder of her three-year-old son is the subject of several conspiracies in the plot of the novel, with several characters accusing either the Jews or the Nazis of being behind the crime.

The novel ends with Roosevelt winning an emergency election for president and restoring history to its real course by entering into World War II on the side of the Allies after the Japanese attack Pearl Harbor.

The veracity of these accusations are disputed by historians.
