" The question that confronts revolutionaries is never simply whether the workers (or peasants) are capable of taking control of the means of production, and reorganizing production on democratic and libertarian lines (like the workers and peasants collectives in Spain). Nor is it even whether they are capable of establishing within cities and villages organs of self-government (as in the many cases of workers councils). From the Paris Commune to the Zapatista rebellion we know that these things can be done.

The question is almost always whether they can do these things over a prolonged period of time under conditions of war and general social breakdown. These are the conditions under which revolutionary opportunities are most likely to occur. It is precisely under these conditions that the limits of the revolutionary movement as a whole have revealed themselves. "
