Why is this novel considered a part of anti-war literature?

Published in 1954 early in the Cold War, Lord of the Flies is firmly rooted in the sociopolitical concerns of its era. The novel alludes to the Cold War conflict between liberal democracy and totalitarian communism. Ralph represents the liberal tradition, while Jack, before he succumbs to total anarchy, represents the kind of military dictatorship that, for mid-century America and Great Britain, characterized the communist system. It is also notable that Golding sets the novel in what appears to be a future human reality, one that is in crisis after atomic war. Golding's novel capitalizes on public paranoia surrounding the atom bomb which, due to the arms race of the Cold War, was at a high. Golding's negative depiction of Jack, who represents an anti-democratic political system, and his suggestion of the reality of atomic war, present the novel as a gesture of support for the Western position in the Cold War.
