@Bob_A_Mickelson:
That might be true now in the Global Rules but wasn’t in Pacific 40. I’ll look into it.
Based on the Errata for Pac40, that’s incorrect. The current wording from the errata states: The United States may not declare war on Japan unless Japan first declares war on it or makes an unprovoked declaration of war against the United Kingdom or ANZAC.
There is an implication of non exclusivity because if Japan was required to declare war on the US there wouldn’t be an “or makes an unprovoked declaration of war against the United Kingdom or ANZAC.”
**Special Comments and Clarifications Related to Neutral Powers
In the event that a power at war attacks a sea zone containing units belonging to a power with which it is already at war and units belonging to a power with which it is not at war, the latter power’s units are ignored. Those units will not participate in the battle in any way, and a state of war with that power will not result.**
And per the FAQ posts:
@Krieghund:
@LuckyDay:
However, if Japan attacks the Dutch on J1, then they are at war with the Dutch, UK/anzac and the US immediately and really no declaration of war is needed because of an unprovoked declaration of war by Japan.
Not exactly. If Japan declares war on UK/ANZAC on J1, war with the US does not immediately result. It does, however, give the US the ability to declare war on Japan on any subsequent turn.

@Stoney229:
Great, thank you. So even if Japan makes an unprovoked declaration of war against UK/ANZAC while it is not yet at war the US, then it is not subject to convoy raid by the US at the end of that turn.
Correct.
I believe Pac40 rules have always stated that it’s up to Japan on which power to declare war on, and their hand is never forced to declare war on both UK/ANZAC and the US and they can choose one over the other (though in most instances they probably declare war on both).
