What went wrong with Britain's supposedly sound prewar Pacific strategy?
Short answerWar with Germany and Italy consumed the planned forces, and the final two-battleship deployment revealed weakness rather than deterring Japan.
NotesWar with Germany and then Italy produced the worst-case sequence for the prewar Far East strategy, consuming ships intended for Asia before Japan entered the conflict. Effective naval diplomacy required either an unmistakably dominant fleet or a deliberately casual cruiser presence backed by hidden strength. Lone-cruiser demonstrations by HMS Birmingham at Tsingtao and HMS Liverpool during the Asama Maru incident implied greater power behind the ship on scene. Sending only Prince of Wales and Repulse instead exposed the limit of what Britain could spare. The strategic failure was therefore also a failure of signaling, not simply a judgment about the two ships' tactical qualities.
