......Unquestionably, Lindbergh himself was responsible for much of the controversy that arose in the postwar years over his isolationism. To the end of his life, he never admitted he was wrong about anything he had said or done. Unlike Anne, who acknowledged that “we were both very blind, especially in the beginning, to the worst evils of the Nazi system,” he uttered no word of remorse or apology for his uncritical attitude toward the horrors of Hitler’s regime. When his wartime journals were published in 1970, Lindbergh defiantly equated the Nazis’ wholesale murder of Jews with other war crimes, including the brutality of some American troops toward Japanese prisoners of war. He still insisted that the United States had made a mistake in entering the war.
“Like many civilized people in this country and abroad, he could not comprehend the radical evil of Nazism,” The New York Times wrote about Lindbergh and his journals. “Even in the retrospect of a quarter-century, he is unable to grasp it.…[T]here is simply no comparison between individual misdeeds of American soldiers toward dead or captured Japanese and the coldly planned, systematically executed German government policy of murdering or enslaving Jews, Slavs, and other ‘inferior’ people.…The world is admittedly not what Americans–or anyone else–would like, but it is decidedly better than it would have been if the United States had not helped to defeat German and Japanese militarism.…If any war can be said to be worth fighting and winning, it was World War II.”
(Also those wartime journals were edited to remove the worst Jew hating excesses, though there were still plenty in there.)
