The uncertainty of the 1920s and 1930s complicates judgments about choices that later proved costly. The combined conflict was foreseeable to an extent, but war with Japan, Italy, and Germany remained the nightmare case rather than the baseline for every cabinet decision. Planners also failed to foresee the fall of France and its consequences for French Indochina, Japan, Malaya, and Singapore. Britain then fought in the Mediterranean, North Africa, Europe, the Atlantic, and the Indian Ocean while its Far Eastern position deteriorated. Scarce escorts and auxiliary vessels mattered because the main fleet had few options across so many theatres.
