Allies must share the cost of persistent presence

A large navy can act as the response force above allied patrol ships, but carrying that role alone concentrates cost and political pressure. Britain at its imperial peak still operated alongside other European, American, Russian, and Japanese naval powers. Britain also began shifting local presence and infrastructure toward Commonwealth navies rather than funding every station centrally. The post-Cold War assumption that the United States could absorb the whole burden works only until American voters and legislators question the price. Durable conflict management therefore depends on allies maintaining interoperable local forces rather than treating a leading navy as a free substitute for their own capacity.
