Staying out?! No, all that was needed was for FDR to tell Stalin to fight the Germans and give him the proper supplies to do so, while at the same time, telling Stalin that Russia had been on Hitlers side so don’t get any cute ideas. The D-Day invasion should have been from Greece such as to take over Eastern Europe for the Western Powers. FDR was Stalin’s b***h and only on his death bed did FDR realize that America had been a useful idiot for Stalin’s evil.

Lol. USSR had been far from being the major business partner of The Third Reich. FDR knew that. And FDR knew which countries imposed the harsh Versailles treaty on Germany, which countries signed the Munich agreement with Hitler.
