Alliances resemble insurance because each member hopes its partners will help in a crisis while accepting obligations in return. Armed forces are compared with emergency services that must already be available when needed. The navy's continuing activity is likened to an ambulance service, air-force patrols to policing, and the army's preparation in barracks to a fire service waiting for a call. Those analogies distinguish a promise of outside help from a force's own readiness. Training and capacity cannot wait until the emergency that requires them.

Alliances as insurance, armed forces as emergency services
Alliances provide reciprocal promises of help, while forces need the readiness to respond when a crisis arrives.
