Suicide attack
Suicide attacks include both Suicide terrorism—terrorism often defined as any action "intended to cause death or serious bodily harm to civilians or non-combatants" for the purpose of intimidation—and suicide attacks not targeting non-combatants. An alternative definition is provided by Jason Burke, a journalist who has lived among Islamic militants, and suggests that most define terrorism as 'the use or threat of serious violence' to advance some kind of 'cause', stressing that terrorism is a tactic. Academic Fred Halliday, has written that assigning the descriptor of 'terrorist' or 'terrorism' to the actions of a group is a tactic used by states to deny 'legitimacy' and 'rights to protest and rebel'.
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".
