I’d like to emphasize that with the Allies, the goal is to remove Axis initiative, so think about some of the things Sun Tzu wrote about with the ultimate goal of forcing the Axis into defensive buys instead of aggressive ones. From that point forward you can starve them of resources and ultimately force them to concede.
With that being said, some things to remember:
Japan can only win the game if the US does nothing in the Pacific. So while you are waiting to join the war, get ships in the Pacific with a general outline of matching Japan’s fleet size and never splitting your own fleet. This basically means 1 Battleship and 2 Carriers in the Pacific. You have enough planes to fill those carriers. Consolidate on Hawaii and follow Sun Tzu’s strategy to beat your enemy to the position of strength. Japan has a much harder time replacing her ships than the US does - so trading ships with Japan is not a bad thing, particularly early.
The US can assist in Europe by establishing a Convoy against Italy. Make sure your US2 and US3 purchases include subs. This is the fastest way the US can assist with the European War Effort. Placing 2-3 SS off of Italy really hurts their income.
The US strategy of getting the SS into the Med goes hand in hand with the UK plan - which is two fold:
First is to defend London. Purchase a large amount of Inf on UK1 and possibly a Ftr (depending if you elected to scramble on the G1 attack).
Second is to neuter the Italian Navy. Trading ships with Italy is fine, as Italy finds it much harder to place a fleet once she loses it. Even if it costs the UK most of her naval presence in the Med, slowing down Italy’s expansion takes pressure off of Cairo which is generally the lynchpin of a European winning strategy.
Further, this strategy opens the door for the US to stage off of Gibraltar and follow another of Sun Tzu’s writings: Strategic Positioning. The ability for the Allies to mass their fleets at Gibraltar through UK purchases in Canada and the US purchases allows you to consolidate into a single place of power (another Sun Tzu strategy). This coincides with another Sun Tzu writing: Confuse the Opponent. By staging in Gibraltar the Allies threaten every major IC in Europe:
-N.Italy
-S.Italy
-W.Germany
-In a 1-2 punch you can take Denmark and then land on Berlin
Above all, remember this when playing as the Allies: Be ever ready to change strategy according
to the changing conditions of the opponent.
