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'.
Islamic terrorism
Islamist-based fundamentalist terrorism against Western nations and the U.S. in particular, has numerous motivations and takes place the larger context of a complex and tense relationship between the 'West' and the Arab and Muslim 'world,' which is highlighted in the previous section on motivations and Islamic terrorism. Identity-based theoretical frameworks, including theories of social identity, social categorization theory, and psychodynamics are used to explain the reasons terrorism occurs.
