Think you’re overreaching here. FDR was a neo-socialist but wasn’t a Commie red. Both he and Churchill would’ve loved to see the only outcome of the Nazi menace be an invasion of the USSR ... there is zero evidence that Roosevelt was more friendly with Stalin. At that time, Stalin had no friends. He’d just murdered 30 million of his own people during the 1930s and this was widely known. FDR was just another enlightened Westerner who believed in high taxes and good paternalistic Government — exactly what Western Europe is today and became immediately after WWII.
If Hitler invaded hell I would make at least a favorable reference to the devil in the House of Commons.- Winston Churchill
