Britain and the United States cannot leave the other to defeat Japan alone

Even if Japan initially attacks only one Anglo-American power, the other cannot accept a solo victory that would displace its own strategic position in Asia.

Question

Could this stronger British position lead Japan to fight only the United States?

Short answer

No: Britain and the United States each has too much at stake in Asia to let the other defeat Japan alone and dominate the postwar regional balance.

Notes

Britain and the United States each expected its infrastructure and force structure to support eventual victory in a war against Japan alone. Either power's solo victory would threaten the other's position in the Far East. Each therefore has a strategic reason to intervene if Japan fights the other. In this assessment, a stronger British fleet still leaves Japan facing both powers.
