Acting Costa Rican President José “Don Pepe”Figueres Ferrer takes a sledgehammer to the Cuartel Bellavista military barracks, 1948
The 22 countries which have abolished their militaries or were founded without one are uniformly tiny, isolated, and often island nations. In many cases, these states maintain national police or paramilitary forces for internal protection (some might say from their own citizens in the event of a popular uprising to effect regime change), maritime defence patrols, or are defended by their former colonial masters. Some might say they are at little risk of invasion because there’s nothing more to take and few to fight back!
Although countries with armies may be more complex and have extensive economic and foreign policy agendas, there is no reason why they, too, could not take the first step in abolishing their large and costly militaries. One country’s standing army can only be an implied threat against other nations. When a country has an army, there is every incentive to put it to aggressive use.
