The word "terrorism" was inventend to describe the policy of the French republic after the French revolution and was claimed by the Republican Themselves. Today "terrorism" is used in the rhetoric of power to present an adversary as "absolute evil". The word is reserved to non official groups unable to battle professional armies and so it is discarded when the question is tu judge the acts of those armies. The result is that in today's violent conflict, only the weakest can bel labeled "terrorist" whiche makes the use of the word a very powerful tool in favor of the dominant order.
