I think a few here is fond of the old Franklin Delano Roosevelt, but looking into the actions that he did during the years into the prelude of World War 2 was really interesting. At his behest, he supplied Joseph Stalin and the whole Soviet Union of military equipment and intelligence to prepare for the Nazis. I really don't think that Americans during at the time was on board with supplying another enemy, the communists, with their own handmade products just to hold off the Reich.
Let's not get started with the internment camps he did against Americans of Japanese lineage after the Pearl Harbor attacks, how the Democrats were tight-lipped about it to this day, and the communist project that the former First Lady, Eleanor Roosevelt did in Arthurdale, Virginia, that was still left untold on how many people died due to starvation on that god forsaken experiment of hers.
He praised fascisms but also covered up the holodomor and Katyn massacre and called Stalin a friend of democracy so either loved authoritarianism of all stripes or had zero principals and went with whatever got him what he wanted. He also had polio and we know now that people who had polio in childhood seem to be at somewhat increased risk of being hospitalized for a psychiatric disorder later in life so his brain could of been addled and fucked.
