And without wishing to linger further on the Marxist debate around war and revolution, anarchists were historically confronted by the very same dilemma. For some, anti-militarism was a categorical imperative – as it remains now – while for others, wars of resistance against domination were an obligation. And if the “theory” seemed to be clear in its opposition, anarchist practice always revealed a more complex political reality. In the three “great revolutions” of European anarchism – the Paris Commune, the Russian Revolution, the Spanish Revolution –, anarchists never acted alone. They were always part of broader fronts of actors who did not share the anarchist vision, but which by itself did not prevent them from engaging militarily. But then this was the failure of the anarchists, some contend; a judgement whose soundness rests only on the clarity of ideology and hindsight.
