@Marshmallow-of-War ANZAC DOW is not always dumb. Sometimes it allows a key ship block or prevents transports in disputed zones from picking up soldiers. I have seen it happen a handful of times.
Completely true! The ANZAC declaration following a UK Pacific ship move is a classic! I can’t imagine anyone taking issue with that.
However, you’re ignoring the second half of that…
It’s taking the Carolines after initiating a war that leaves the US out of the fight that is the issue, leaving the transports vulnerable and stripping defenses from ANZAC itself. I can’t imagine a scenario where that would be wise.
