Terrorism
Terrorist acts frequently have a political purpose. Some official, governmental definitions of terrorism use the criterion of the illegitimacy or unlawfulness of the act. to distinguish between actions authorized by a government (and thus "lawful") and those of other actors, including individuals and small groups. For example, carrying out a strategic bombing on an enemy city, which is designed to affect civilian support for a cause, would not be considered terrorism if it were authorized by a government. This criterion is inherently problematic and is not universally accepted, because: it denies the existence of state terrorism. An associated term is violent non-state actor.
Revolutionary terror
On the other hand, they opposed individual terror, which has been used earlier by the People's Will organization. According to Trotsky: "The damaging of machines by workers, for example, is terrorism in this strict sense of the word. The killing of an employer, a threat to set fire to a factory or a death threat to its owner, an assassination attempt, with revolver in hand, against a government minister—all these are terrorist acts in the full and authentic sense. However, anyone who has an idea of the true nature of international Social Democracy ought to know that it has always opposed "this kind" of terrorism and does so in the most irreconcilable way".
