I'm not sure of the generally accepted names, but how close am I with a list like this:
Eastern Europe (Germany/Poland/Russia)
Northwest Europe (Germany, Britain, France, Low Countries, Norway)
Finland (Finland, Russia)
Mediterranean (North Africa/Italy/Greece)
China-Burma-India (Japan, China, Burma, India, SE Asia)
Southwest Pacific (Solomons, New Guinea, Australia)
Central Pacific (Hawaii, Midway, Japan)
Aleutian Islands (Alaska)
Is that pretty complete?
