Well the issue was in doubt at times, but that was then, and now all the doubt is gone, we know the outcome so it's considerabley easier to predict that the USSR will not surrender, even though Russia did make peace with Germany during the war to end all wars.
You're amazingly incorrect on every single count......
...and that may just be the vincible ignorance that allows you to pine for FDR.
First....it has not gone unnoticed that you have ignored the dispositive evidence in my post.
Secondly....Hilter and Stalin had treaties that armed and supported the Blitzkrieg, provided strategic materials to Hitler, and actually taught the SS how to operate concentration camps and conduct mass murder.
These were partners, planning to split Europe between them.
1. Early Nazi propaganda posters included the hammer and sickle.
2. When Hitler began his advances on other countries, Stalin refused to join the nations talking of stopping him. Stalin was, in fact, pleased that Hitler was destroying the old order throughout Europe. "There will be no parliaments, no trade unions, no armies, no governments....then Stalin will come as the liberator...millions of people will be sitting in concentration camps, hoping someone will liberate them, then Stalin and the Red Army will come and liberate them. That was his plan."
Vladimir Bukovsky.

September 1, 1939, Hitler attacked Poland....on September 17, Stalin attacks from the East. The Soviet radio transmitter in Minsk guided the Nazi bombers attacking Polish cities. Newsreel footage showed the Red Army in Nazi helmets, marching side by side with the SS. One photo shows the hammer and sickle along side the swastika.
a. The Soviet press depicted the battle as a fight against Polish fascism, with the peace-loving Nazi Germany and the Soviet Union fighting aggressive Polish fascism.
4. Hitler and Stalin signed secret protocols to divide up Europe. First, Stalin moved against Finland, November 1939....for the aggression, the USSR was expelled from the League of Nations. Hitler attacked to the West.
a.
Norway was invaded by Hitler with the direct help of the Soviet Union, providing the Soviet naval base near Murmansk. "German Admiral Raeder sent a letter of thanks to the Commander of the Soviet Navy, Kuznetsov."
5. Archival footage shows Nazi and Russian officers partying together. The USSR became the supplier of oil, iron ore, construction materials for Hitler's Blitzkrieg. And trainloads of grain, even while Russians were starving.
a. Communist party members throughout Europe were ordered to sabotage their nation's forces, and
aid the Nazi attackers. The French Communist Party, July 1940: "It is comforting to see workers talking to German soldiers as friends,...'well done, comrades, and keep it up,' ...the brotherhood of man will not be forever a hope, it will become a living reality."
And Franklin Roosevelt knew all of the above.
A pity that you don't.
