Security community
A security community is a region in which a large-scale use of violence (such as war) has become very unlikely or even unthinkable. The term was coined by the prominent political scientist Karl Deutsch in 1957. In their seminal work Political Community and the North Atlantic Area: International Organization in the Light of Historical Experience, Deutsch and his collaborators defined a security community as "a group of people" believing "that they have come to agreement on at least this one point: that common social problems must and can be resolved by processes of 'peaceful change'". Peaceful change was defined as "the resolution of social problems, normally by institutionalized procedures, without resort to large-scale physical force". People in a security community are also bound by the "sense of community", the mutual sympathy, trust, and common interests.
