I have been very conscious of when I use "Nazi" and when I use "German" in the story. I will add "Soviet" and "Russian" to that list! And yes, there were huge problems to having Stalin as an ally. I had read that Roosevelt's promise to Molotov notwithstanding regarding the second front, Churchill was perfectly content to let the Nazis and Stalin's forces (Soviet army?) battle it out to the weakening of both.

Thanks again and onward!
