To escape the intense media scrutiny and public attention following the trial, the Lindberghs move to Europe, residing primarily in England and France.

At the request of the U.S. military, Lindbergh visits Germany and other European countries to assess their air forces. He becomes impressed by the Luftwaffe's capabilities, leading him to overestimate Germany's air power.

Lindbergh is presented with the Service Cross of the German Eagle by Hermann Göring, a high-ranking Nazi official. This award later becomes a source of controversy and criticism.

As tensions rise in Europe, Lindbergh becomes a vocal advocate for American isolationism, arguing that the U.S. should not intervene in European conflicts. His views are based on his assessment of Germany's military strength and his belief that Europe should resolve its own problems.
