Strange that nobody answered so far?! In my games going full pac or atl only worked (a little) with the US when the British did very well. I even tried to take Borneo but ended up with a japanese fleet that threatened the US westcoast.
So in summary we managed to take some pressure from the Russians but came in a - in my opinion - much worse position. Because then we had to build units to defend the american homeland…
Any ideas what we did wrong?
