All acts of terrorism, all the outrages which have struck and which strike the imagination of men, have been and are either offensive actions or defensive actions. If they form part of an offensive strategy, experience has shown for a long time that they are always doomed to fail. If, on the other hand, they form part of a defensive strategy, experience shows that these acts can expect some success, which, however, is only momentary and precarious. The attempts of the Palestinians and the Irish, for instance, are offensive acts of terrorism; on the other hand the Piazza Fontana bomb and the kidnapping of Moro, for instance, are defensive acts.
