Gunboat Diplomacy
E2. Naval, defence and maritime law enforcementDefinition
Coercive use of naval presence (Cable).
Gunboat diplomacy is the use of naval presence or the limited threat of force, short of war, to support a state’s foreign-policy objectives. James Cable’s study Gunboat Diplomacy 1919 to 1991 defined it as the use or threat of limited naval force to secure advantage or avert loss in an international dispute, and sorted it into definitive, purposeful, catalytic, and expressive force. The Victorian era furnished the archetypes; the term still describes carrier deployments and freedom-of-navigation operations that signal resolve without firing. It is coercive diplomacy delivered through the mobility and visibility of warships.
