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'.
Alberto Abadie
Abadie's view is that the level of political freedom, not poverty, explains terrorism. As he told the Harvard Gazette, 'In the past, we heard people refer to the strong link between terrorism and poverty, but in fact when you look at the data, it's not there. This is true not only for events of international terrorism, as previous studies have shown, but perhaps more surprisingly also for the overall level of terrorism, both of domestic and of foreign origin.' His research indicated that it is areas with intermediate levels of political freedom that experience the most terrorism. Both societies with high levels of political freedom and authoritarian regimes have low levels of terrorism. Autocratic nation's 'Tight control and repressive practices keep terrorist activities in check, while nations making the transition to more open, democratic governments may be politically unstable, which makes them more vulnerable.'
