When you’re close to taking Sydney as a final VC, u’ll find yourself producing over 90 IPC’s hehe… The trick with the US is to destroy Japan’s Navy piece by piece. This allows Hawaii and Sydney to be safe from a Japanese invasion wich denies them victory. U’ll find that the caroline islands are also very important. This gives a 1-turn passage into mainland China where you can almost land anywhere and create a gap in that japanese front (or, even better, if the japanese player built an IC, to take it away :)), and please land before India is captured.
