Don’t attack Russia from the east. You’ll dilute your forces out and the territories aren’t worth it. “That’s Stalin’s territory! You want your armies over HERE.” Use your time in the game keeping the US bogged down the Pacific, so they can’t send forces into Europe.
Concentrate on taking the DEI first before any of the other Allies in the Pacific get a chance, preferably on J2. Build transports on J1 so you’ll have greater spread throughout the Pacific in taking the DEI oil islands. On J2 launch a monster attack with most of your fleet to capture them all. Leave enough boats to protect your transports so you can use them later to reinforce everywhere. After that, try to match the US boat for boat, bring back your airplanes from the mainland gradually to land on carriers, and generally maintain a stalemate with the US while sending enough troops into Asia to knockout India. Attack the US fleets once you have numerical superiority if they start ignoring you and sending more stuff into Europe.
Make sure you take as much of the DEI as you can on J2, and don’t let the Allies get a foothold on them or both India and Australia will be impossible. Try to keep China mowed down every turn if you can, but you can afford to lose territory in China compared to the amount of money available in the Pacific. Minor ICs in FIC and Malaya work wonders in keeping the troops coming for the final push too.
