Basically I think that security measures of a purely technological nature, such as guns and crypto, are of real value, but that the great bulk of our security, at least in modern industrialized nations, derives from intangible factors having to do with the social fabric, which are poorly understood by just about everyone. If that is true, then those who wish to use the Internet as a tool for enhancing security, freedom, and other good things might wish to turn their efforts away from purely technical fixes and try to develop some understanding of just what the social fabric is, how it works, and how the Internet could enhance it. However this may conflict with the (absolutely reasonable and understandable) desire for privacy.And that quote got me to thinking about technolology and security, and how technology never really replaces human beings, it just makes certain tasks easier, quicker, and more efficient. There was a lot of talk about this sort of thing around the early 90s, when certain security experts were promoting the use of strong cryptography and digital agents that would choose what products we would buy and spend our money for us.
As it turns out, most of those security experts seem to be changing their mind. There are several reasons for this, chief among them fallibility and, quite frankly, a lack of demand. It is impossible to build an infallible system (at least, it's impossible to recognize that you have built such a system), but even if you had accomplished such a feat, what good would it be? A perfectly secure system is also a perfectly useless system. Besides that, you have human ignorance to contend with. How many of you actually encrypt your email? It sounds odd, but most people don't even notice the little yellow lock that comes up in their browser when they are using a secure site.
Applying this to our military, there are some who advocate technology (specifically airpower) as a replacement for the grunt. The recent war in Iraq stands in stark contrast to these arguments, despite the fact that the civilian planners overruled the military's request for additional ground forces. In fact, Rumsfeld and his civilian advisors had wanted to send significantly fewer ground forces, because they believed that airpower could do virtually everything by itself. The only reason there were as many as there were was because General Franks fought long and hard for increased ground forces (being a good soldier, you never heard him complain, but I suspect there will come a time when you hear about this sort of thing in his memoirs).
None of which is to say that airpower or technology are not necessary, nor do I think that ground forces alone can win a modern war. The major lesson of this war is that we need to have balanced forces in order to respond with flexibility and depth to the varied and changing threats our country faces. Technology plays a large part in this, as it makes our forces more effective and more likely to succeed. But, to paraphrase a common argument, we need to keep in mind that weapons don't fight wars, soldiers do. While technology we used provided us with a great deal of security, its also true that the social fabric of our armed forces were undeniably important in the victory.
One thing Stephenson points to is an excerpt from a Sherlock Holmes novel in which Holmes argues:
...the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful country-side...The pressure of public opinion can do in the town what the law cannot accomplish...But look at these lonely houses, each in its own fields, filled for the most part with poor ignorant folk who know little of the law. Think of the deeds of hellish cruelty, the hidden wickedness which may go on, year in, year out, in such places, and none the wiser.Once again, the war in Iraq provides us with a great example. Embedding reporters in our units was a controversial move, and there are several reasons the decision could have been made. One reason may very well have been that having reporters around while we fought the war may have made our troops behave better than they would have otherwise. So when we watch the reports on TV, all we see are the professional, honorable soldiers who bravely fought an enemy which was fighting dirty (because embedding reporters revealed that as well).
Communications technology made embedding reporters possible, but it was the complex social interactions that really made it work (well, to our benefit at least). We don't derive security straight from technology, we use it to bolster our already existing social constructs, and the further our technology progresses, the easier and more efficient security becomes.
