An Anglo-Japanese alliance could dominate the Pacific

Would Britain’s Dominions still press to end the Anglo-Japanese Alliance after an American defeat?

They would have less reason to do so because Japan’s partnership with Britain would protect Dominion security while no strong United States remained to demand the alliance’s end.

A stronger Japan and an intact Anglo-Japanese alliance would become the dominant security structure in a Pacific no longer checked by a competitive United States. Britain’s Dominions could value the alliance because Japan would be less likely to attack territories protected by its principal partner. Under the Dominion arrangement described here, the British government would ultimately control alliance policy even when Dominion politicians objected. Royal visits and dynastic ties are offered as speculative ways to reinforce the relationship, with marriage scenarios remaining explicitly contingent. Removing American power changes the Dominions’ incentives as well as the relative strength of Britain and Japan.
