Is it possible or not, given the present conditions in our continent, to achieve it (socialist power, that is) by peaceful means? We emphatically answer that, in the great majority of cases, this is not possible. The most that could be achieved would be the formal takeover of the bourgeois superstructure of power and the transition to socialism of that government which, under the established bourgeois legal system, having achieved formal power will still have to wage a very violent struggle against all who attempt, in one way or another, to check its progress toward new social structures.
