I'm the US player in question, and I feel that my side of the plan should be filled in to complete the image being painted here:
Firstly, we're most likely going to end up being fascist, even though we'd ideally rather not be, because we both have plans to wage wars against democracies.
My plan begins from the instant the game starts: I intend to improve relations with Japan as much as I possibly can, and, if there is an option to do such a thing, sign an agreement with Japan that I won't expand any further into Southeast Asia if they don't attack any of my territory, including the Philippines.
Next, I'll begin stockpiling in preparation to wage War Plan Red, but I'll hold off on it until 1940, after France falls and Heruure (Sweden) has taken Norway and Denmark (and, as a result of this, given me control of Greenland and Iceland). The period between the start of the game and 1940 is when I will be "very quiet" and intend to utterly drown Sweden in lend-lease. After I get Iceland and Greenland and France has fallen, I'll call back as many of my lend-lease materials as I can and use my stockpiled supplies to launch an invasion of Canada and take control of the British islands in the Caribbean.
With Japan attacking Britain's possessions in the Pacific, me attacking Britain's dominions in North America, Italy taking Britain's colonies in Africa, and Germany attacking the British Isles, and Sweden taking out anything from the British navy that dares leave port, we figure Great Britain will be pretty powerless to stop any of us.
My invasion plan of Canada calls for mostly a mechanized/armored land invasion with air support, with ships simply preventing blockades of the homeland and stopping reinforcements to the soon-to-be-homeland, while having a comparatively small-scale invasion of the British Caribbean possessions. It is from this that Heruure and I agreed that I should give 15% of my naval production, slightly less as much of my aircraft production, and closer to 10% of my tank production to Sweden, since his main concerns involve control of the waters around him while I'll mostly be fighting the longest-front land war between any two singular countries in human history.
After Britain has been thoroughly disposed of, with her land sliced up and handed out to those who are most interested in it, we have been considering next turning to Russia, with any involvement I have in that theater, if I get involved directly at all, being such where I will give my spoils of war to Japan as we both attack from the eastern side and Germany, Italy, and Sweden attack from the west.
After this (or after the defeat of Britain if we ultimately decide against interfering with Russia), ideally, if these two actions are possible, I would like to switch back into a democratic form of government and re-activate undisturbed isolation as a nation that occupies the entire northern more than two thirds of North America and spans over half of the Earth's surface end-to-end (Iceland to either the Philippines or Guam, depending on if I decide to give the Philippines independence, or if they even want it at that point).
We're extremely excited to see how the post-war landscape looks, and which countries might develop an equivalent to the Cold War.
With all of this data here, how is our war plan?
