ABDA's command problem and the value of a visible Allied force

Could a different commander have saved ABDA from defeat in early 1942?

Only with more forces and a unified Allied command; a carrier-backed Force Z and a senior theatre commander could have improved coordination and deterrence.

Replacing ABDA's commander would achieve little unless the new officer also received more forces and real authority. A viable core could have grown from a reconstituted Force Z built around a Royal Navy carrier, Prince of Wales, Repulse, cruisers, and destroyers. The deeper failure was the absence of a coherent command structure able to coordinate Allied land, air, and naval forces before the Japanese offensive. The proposal places a very senior British commander over subordinate service commanders and the Commonwealth, Dutch, and American forces across the Indian Ocean and Southeast Asia. Such an appointment would organize scarce resources while also signalling that Britain treated the theatre as a major strategic commitment. A later follow-up suggests that Roger Keyes and Douglas MacArthur might have divided the theatre pragmatically, with MacArthur handling land operations while Keyes managed air-sea coordination and coalition politics. Admiral Ernest King might also have accepted that arrangement because he respected Keyes, disliked MacArthur, and could treat Southeast Asia as a primarily British-Commonwealth theatre. The commander's prestige and the visible force behind him would therefore contribute to deterrence as well as battlefield control. Command arrangements, force availability, and political credibility have to be designed together.
