USA = United States of Africa: Turn South Africa communist, throw all the imperial pigs out of Africa and take our freedom from the evil colonialists! Oh, wait... 
As Japan, try to defeat UK Pacific fleet before war with USA by starting the war with Allies early in 1940 instead of late 1941! Damage them as much as possible (maybe even invading Britain) until I see war with USA is inevitable. Then Pearl Harbor must will be even more devastating than in real life, allowing Imperial Japanese Navy to reign supreme in both the Pacific and Atlantic! Then invade Panama and South America, locking the Americans in North America with the rest of the world dominated by Axis.
Communist France, similar to latest WWW. I really like the last one, looks interesting!
