The counterfactual stays within one or two logical steps of the historical divergence. By late 1941 the fate of Italy, the Atlantic raiders, Indochina, Greece, and the Mediterranean has already changed which ships are available. A fleet of roughly ten capital ships and several carriers in the Far East is possible, but choosing exact vessels and operations would stack assumptions on assumptions. Beyond that point, disciplined analysis gives way to writing one particular fictional timeline.
