I must admit, I have only recently started AA1942. I have bee playing the Revised. I am in the 5 or 6th game. I have only had 1 game where anyone has tried anything along the lines of a naval attack by the US. I let them come to me, ignored any expansions into Australia, then wiped them out.
Any strategy regarding the US mounting anything on Japan with ships is an automatic loser. Even if I didn’t wipe them out and just held them off with planes, even losing an island or two, for every $1 spent, they would have to spend $2. In the end, I can shift my fighters to the front lines quickly. The US can’t, and they are likely to be left with very expensive ships that can do nothing for them. You really have to have a poorly played Japan for this to work. The US navy has to be used against German operations.
As far as an IC in Sinkiang, if you could hold it, but you can’t. Not unless the Russians give up the high IPC territiories even faster to the Germans. I suppose if Japan made some early mistakes, (hence a poorly played Japan) or got really unlucky with their roles.
But believe me, twenty years of AA and the basics have not changed. Though I have only played 6 games or 1942, the changes in the game are very minor. Maybe in the Historical edition or the Global game such a strategy would work.
