Never none has ever heard that an Englishman, Frenchman, American has wrapped with the explosive, and detonated it within a bus, market, or a state institution.
Western fundamentalism is deeply woven into democratic system, with no need for individuals to decide a desperate move. For, their governments, intelligence agencies, and the military... work for them and in " generally acceptable ways."
PHILOSOPHY OF LIBERTY
To take someone's life in "a legitimate" bombing campaign, as an action of the official army, or intelligence service, while accompanied by the Media simply announcing that someone or a group of people " was killed " for a reason is a quite normal thing. Behind of these happenings always stand a complete society, never individual who pulled the trigger.
Usually, when in the search for "a known terrorist", an airplane attack kills a group of innocent civilians in their own house, there follows a typical explanation: it was an "error", or the information from the terrain "was not accurate enough". In short, never anybody has been convicted of any such an act of a mass murder. The public has never got upset when such things take place.
Therefore, within a western democracy there is no need for "desperate moves", or individual acts of revenge for the injustice.
