The Enclave is a paramilitary organization[3][12] and quasi-state(Note) dedicated to the project of an all-inclusive holocaust of non-members, whom they dehumanize as “genetic non-compliance offenders.”[7][13][14] It is the direct continuation of a pre-War American deep state organization consisting of high-ranking political, military, and corporate figures.[15] It claims to be the direct continuation of the United States and its government,[16] despite seizing power by subverting continuity of government protocols and murdering non-Enclave government survivors[17] in the name of continuing the war against the concept of communism.[4][18]

Enclave ideology eventually incorporated pseudo-scientific concepts like social Darwinism[7] and racism[19][20] towards non-Enclave humans, super mutants and ghouls. Racism led to genocide; all humans outside the Enclave were designated as near-human mutants to be exterminated.[21][5] The plans to wipe humanity out worldwide,[8] establish a racially pure state of “true humans,”[14] coupled with its authoritarian structure, use of slaves,[22] human experimentation,[14] torture,[23] and unprovoked attacks on American citizens,[24] resulted in the Enclave being seen by the rest of humanity as an evil, tyrannical force, identified by even its former members as a fascist[2][3][25] remnant of the pre-War government,[26] sometimes simply called “the rich old bastards who didn’t want to give up their power.”[27]
