Acts of sabotage are very important. It is necessary to distinguish clearly between sabotage, a revolutionary and highly effective method of warfare, and terrorism, a measure that is generally ineffective and in-discriminate in its results, since it often makes victims of innocent people and destroys a large number of lives that would be valuable to the revolution. Terrorism should be considered a valuable tactic when it is used to put to death some noted leader of the oppressing forces well known for his cruelty, his efficiency in repression, or other quality that makes his elimination useful. But the killing of persons of small importance is never advisable, since it brings on an increase of reprisals, including deaths.

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.
