Suggestion for USW in A&A 1914:
USA has no fixed war Entry in the game.
It collects 20 IPCs income every Round without beeing allowed to build or move troops.
USA was never a true neutral state. Because of that, it sends from R1 on (after collecting its income) 10 IPCs to BE (5) and France (5).
This financial help will continue every Round as long as GE won´t declare USW or
the US enters war because of the fall of the tzar (first economical collapse of Russia).
From R2 on Germany can declare USW to stop this american help. At the beginning
of every Round it can roll for every sub that is located in the historical USW-SZ 2,3,4,7,8,9,15 one dice. The result will be splitted up between USA and BE. (If uneven BE will get the higher lost)
IF US suffer two times because of this they will declare war against the CPs.
