Interception-attrition operations begin with submarines shadowing an enemy. Land-based and carrier aircraft then strike before cruisers and destroyers attempt night attacks. Applying this sequence against Britain creates a geographic problem because its force would advance from Singapore through waters bordered by French, Dutch, and American territory. Japan would have to neutralize those powers, fight them, or concede room for British movement. Japanese long-range torpedoes mattered, but British radar, night-fighting experience, and habitual zig-zagging could limit the expected payoff.
