third post down in the above linked thread has LH’s quote on France-Germany-Russia triangle.
The diplomatic aspect of the Nazi/Soviet relationship will be ignored in part. Either can attack each other turn one, but what would they be able to bring to bear, that will be the question. What will be remembered will be the ‘friendly’ relationship in terms of offensive ability on the front. Both will be setup in defensive positions at best, but nothing too deep. The vast expanse of Russia will be the a problem, too much ground for Russia to defend early but too much ground for Germany to reinforce quickly.
The question will be is there enough in France to keep Germany’s attention? Could Germany split their forces and go both directions right away? Can they chip away France’s 3 territories over a couple turns, will moving to Moscow. LH has mentioned about SeaLion, so it will also take UK a couple turns to mobilize to the continent. US also will be delayed. How much can be grabbed and as quickly as possible. Depending on the final numbers of units involved in the setup, both may be possible, or just let the Italians take France and ignore Africa.
