While this is a fictional tale, it does use accurate depictions of the time; for instance, Charles A. Lindbergh was, in actuality, very Antisemitic. Lindbergh was leader of the America First movement, created in 1940 after Adolf Hitler had invaded Poland, and believed the US should take a neutral position in WWII. He was quoted in Readers Digest in 1939 as saying " We can have peace and security only so long as we band together to preserve that most priceless possession, our inheritance of European blood, only so long as we guard ourselves against attack by foreign armies and dilution by foreign races." He believed in eugenics, that Germany had a 'Jewish' problem, and was close friends with Henry Ford, another well-known Antisemite.
