Jan Fischer, American Soldier In His Military Life

Antimilitarism is the society's social attitude opposed to war between states, and in particular countering arguments based on militarism. Following Hegel's exploration of the relationship between history and violence, antimilistarists argue that there are different types of violence, some of which can be said to be legitimate others non-legitimate. Anarcho-syndicalist Georges Sorel advocated the use of violence as a form of direct action, calling it "revolutionary violence", which he opposed in Reflections on Violence (1908) to the violence inherent in class struggle. Sorel thus followed the International Workingmen's Association theorization of propaganda of the deed.
War, as violence, can be distinguished into war between states, and civil war, in which case class struggle is, according to antimilitarists theorists, a primordial component. Hence, Marx's influence on antimilitarist doctrine was not surprising, although making Marx accountable for the antimilitarist tradition is a large overstatement. The belief in the eternal antimilitarist spirit, present in all places and time, is however a myth because the modern military as an institution is a historic achievement formed during the 18th and 19th centuries, as a by-product of the modern nation-states. Napoleon's invention of conscription is a fundamental progress in the organization of state armies. Later, Prussian militarism would be exposed by 19th century social theorists.
