OK, lets recap, with an eye to responding to some themes in the comments.
First, lets assume for the sake of discussion that there is a form of violence which we call terrorism, which is different on one end, from crime, and on the other, from open warfare, which maintaining some of the features of each.
The three key distinguishing features would be: violence against civilian targets with the intent to damage morale and effect political change; violence not targeted at either political leaders, combatants, or the resources necessary to lead or conduct war or economic life. The targets
trains, airliners, Olympic athletes, airports, cafes, schools, and symbolic buildings
are selected for their maximal dramatic impact, rather than for their substantive impact.
It would be like attacking Los Angeles by blowing up Universal Studios rather than the California Aqueduct.
This is ultimately a philosophy of self-liberating action of praxis. In this philosophy, the actor finds the meaning of his or her life in the liberating acts that they do. Sound familiar? Ill quote (for the 3rd time) Berlin:
The values to which they attached the highest importance were such values as integrity, sincerity, readiness to sacrifice ones life to some inner light, dedication to an ideal for which it is worth sacrificing all that one is, for which it is worth both living and dying. You would have found that they were not primarily interested in knowledge, or in the advancement of science, not interested in political power, not interested in happiness, not interested, above all, in adjustment to life, in finding your place in society, in living at peace with your government, even loyalty to your king, or your republic. You would have found common sense, moderation, was very far from their thoughts. You would have found that they believed in the necessity of fighting for your beliefs to the last breath in your body, and you would have found that they believed in the value of martyrdom as such, no matter what the martyrdom was for. You would have found that they believed that minorities were more holy than majorities, that failure was nobler than success, which had something shoddy and vulgar about it. The very notion of idealism, not in its philosophical sense, but in the ordinary sense in which we use it, that is to say the state of mind of a man who is willing to sacrifice a great deal for principles or some conviction, who is not prepared to sell out, who is prepared to go to the stake for something which he believes, because he believes in it this attitude was relatively new. What people admired was wholeheartedness, sincerity, purity of soul, the ability and readiness to dedicate yourself to your ideal, no matter what it was.
No matter what it was: that is the important thing.
Ive suggested above that there is a philosophical basis for this violence, and Ill go further, and say that to defeat it, you have to understand and manage its philosophical underpinnings, because one of the key features of this kind of violence is that it is both hard to capture the managers, and relatively easy to recruit the agents.
Now here, Ill confess a bias. Im basically a philosophical kind of guy, although that will come as a surprise to my friends in physical space, who know me as the guy who goes Beer!! More Beer!! a lot (not too much Sam Adams any more, though), and so there is the problem at a psychologist has in imputing psychological interpretations to every event.
But Ill restate the above more seriously. It is easy to grow terrorists in this climate. Easiest right now in the Middle East, but Ill suggest that other parts of the world are not all that far behind. We can work had to capture them, build layers of security into our lives, accept some level of tragedy or loss, or we can figure out how to stop growing them.
Now this isnt a call to roll over and play dead, nor to simply give in to the current crop of political demands. In fact, its an argument that as soon as we did give in to the current crop of demands, a whole new set would come up, because if I am right, it is the act of warring against the West and modernity that matters, not any specific goals.
