He may have recanted his affection for the Nazis but Lindbergh was in later years an environmental case with utter contempt for humanity. Just sayin’.
Charles Lindbergh was not a Nazi sympathizer. Following his visits to Germany before the war, he was debriefed by US military intelligence and revealed what he knew about German air power. Although he opposed US involvement in WWII, he volunteered to serve after the US declared war. But FDR not only refused to allow him to serve, but tried everything he could to keep him out of the war—apparently out of spite due to the longstandingb animosity between the two, which seems to have dated back to a dispute over air mail service in the mid-1930’s.
Nonetheless, Lindbergh got into the war courtesy of his friend Henry Ford. His accomplishments included finding a way for Corsair fighter aircraft to double their bomb loads.
Incidentally, if Lindbergh were a Nazi sympathizer, President Eisenhower would never have appointed him a brigadier general.
