Let's get borderline but not quite ASB here, because there needs to be some reason to it. How could WWII affect even more geographical locations?
Latin America: cliche Argentina and some other South American nations join the Axis and threaten the other countries, U.S. goes Monroe Doctrine on them. (Shattered World)
Subsaharan Africa: Purified National Party takes power in South Africa and joins Axis and invades British/French/Belgian/Portuguese territories. (
Berlin/Moscow Axis)
Iberia: Spain joins Axis, attacks Allied Portugal (Shattered World)
Scandinavia: Post-Central Powers Sweden (Admiral Essen situation) ends up in the Axis somehow, or at least involved in the Winter War, thus fighting the Soviets and so indirectly the Allies.
Near East: something involving Turkey/Iran/Afghanistan.
India: Axis agents successfully incite revolt against British rule
Australia: Japanese invasion attempted.
