Neutrality
Explanation:
Charles Lindbergh was the son of a United States Congressman, so is easy to assume he had some political understanding due to this context.
He was the first person to fly alone, through the Atlantic ocean, without stopping. This achievement made him an idol to millions.
Years later, when President Franklin Roosevelt was puhhing an illegal campaign to involve the US into the European war, he took advantage of the fame he had obtained, and actively opposed to this action. It is considered that he became the voice of the great majority of people from the US by taking that position.
He began giving speeches throughout the country, one that was very important was on "Neutrality and War," October 13, 1939.
