Britain's dependence on sea communications made the Royal Navy the traditional senior service, while Japan's earlier isolation and use of ships mainly for movement produced a more complicated naval inheritance. Postwar circumstances then reversed expectations: Japan built a powerful maritime self-defense force, while Britain's NATO commitment to a large army in Germany diverted resources from its navy. The result is presented as a British force mix poorly aligned with present geographic needs. In this interpretation, Britain would now be better matched by a solid army with greater reserve depth alongside comparatively stronger naval and air forces.
