Force Z was too small and too far forward for deterrence

The proposed deterrent advertised nearly everything Britain could immediately spare and placed it at a front-line base. A small visible force also removed uncertainty about whether a larger British battle fleet might still arrive. Concentrating the ships alongside the R-class battleships, Hermes, cruisers, and destroyers already in the Indian Ocean would at least have created the appearance of a substantial fleet. Global commitments in the Atlantic and Mediterranean explain the shortage, but they also made the isolated Singapore deployment strategically brittle. Long wars depend on infrastructure and equipment, so construction decisions made before a crisis determine which credible forces remain available when deterrence is tested.
