If your opponent is buying DD’s with the USA it is unlikely you are playing 2nd edition. You should post on the correct forum to make sure you are receiving the best advice.
Don’t forget about the premier PBEM clubs: AAMC and IAAPA. AAMC is free and IAAPA charges a minimal fee. Both clubs have their own dice rollers (AAMC’s is provided above) and very experienced players. If you are interested in finding out how you rank against good PBEM A&A players, I would recommend checking out these clubs. The good thing about these clubs is that you can play against an opponent of any desired skill level.
The Japan isn’t the main problem. With a decent size Navy (2 hit BB’s hopefully) after Pearl Habor and maybe a buildup of some supporting ships (a few subs or destroyers), the Japanese can hold WUSA at bay even without blockading. However, it’s the German I’m more worried about only having subs and maybe a carrier to contend with).
