You will not find official confirmation that he was a Jew in any book, but he was surrounded only by Zionist advisers headed by Morgentau. The etymology of his name would also indicate that he is a Jew. An official admission that he is a Jew would then close his political career for him. An interesting fact is also his paralysis caused by Polio. He was a promoter of vaccinations against this disease, which infected and paralyzed hundreds of children around the world. Roosevelt was the first case of this disease. Polio is an infection of the nervous system that is transmitted through the fecal-oral or implantation route. You can get such an infection during anal intercourse, when the mucosa breaks or when you take it from your ass to your mouth. The conspiracy theories about Kermit Roosevelt, Walt Disney, Adolf Hitler and Angela Merkel are very interesting and at times very probable.
