In the 1920s, Italian fascists adopted the Roman salute to symbolize their claim to have revitalized Italy on the model of ancient Rome. This was quickly copied by the German Nazis, creating the Nazi salute. The similarity to the Bellamy salute led to confusion, especially during World War II. From 1939 until the attack on Pearl Harbor, detractors of Americans who argued against intervention in World War II produced propaganda using the salute to lessen those Americans' reputations. Among the anti-interventionist Americans was aviation pioneer Charles Lindbergh. Supporters of Lindbergh's views would claim that Lindbergh did not support Adolf Hitler, and that pictures of him appearing to do the Nazi salute were actually pictures of him using the Bellamy salute. In his Pulitzer prize winning biography Lindbergh, author A. Scott Berg explains that interventionist propagandists would photograph Lindbergh and other isolationists using this salute from an angle that left out the American flag, so it would be indistinguishable from the Hitler salute to observers.
In order to prevent further confusion or controversy, President Franklin D. Roosevelt instituted the hand-over-the-heart gesture as the salute to be rendered by civilians during the Pledge of Allegiance and the national anthem in the United States, instead of the Bellamy salute. This was done when Congress officially amended the Flag Code on 22 December 1942.
