I disagree with you nakshtrap. The definition of "terrorist" is an opportunistic one. The greater power calls the lessor power a terrorist. The greater power wishes for a conventional war, but the lessor power realizes they have no chance of winning a conventional war, so they choose to fight an unconventional war.
The notion that war is fought by soldiers alone is a disturbing misprint on what is perceived as "civilized." In our particular societies, we have separated citizens into castes. They fight, or they do not. They are military or they are civilian.
The advertised notion is that those who fight, those in the military, should be the only ones targeted in a war. But, this is a notion of convenience and of arrogance. One cannot dictate to the opposition just how a war is to be fought. One can only deal with a war in the manner it is presented. One doesn't stay "protected" by merely choosing not to fight. The ruling caste cannot hide behind their warrior caste and think they are immune to injury or repercussions, merely because they are not warriors.
The barbarism of war exists. The barbarism of illegal actions are a balancing contrast to the civility of modern day life. The military/police serves as a barbaric extension of a civilized society but, the actions of persons within that civilized bubble, which foster hostility and suffrage in other nations, cannot be dismissed merely because they hold a teacup. There are consequences to exploitation of other nations, of those less fortunate, those less civilized. A war fought on lands far from home does not justify an opulant lifestyle at home. In fact, it condemns it.
