I saw an interesting entry about emergent terrorism.
I have always believed that terrorism is emergent in a lot of ways. Steven Johnson points out in his book, Emergence that not all emergence is good. I think Danny Hillis once pointed out that destruction works to beat up an ordered system such as US troops in Desert Storm, but has difficulty fighting chaos, such as terrorism. So how do we combant chaotic emergent threats? David discusses this in his Art of Peace entry a bit. I think you have to understand the conditions that cause the emergence as well as the the nature of the "units". I think one of the big problems in our quest to understand terrorism is that we think that "they" are not humans. "How could humans hate America? How could humans try to hurt us?" "They're evil, so they're not human in the same way we are human." Well, "they" are among "us".
I think the more quickly we decide that we are humans fighting humans and focus on the conditions that cause terrorism, the more effectively we will combat it. I think that using force and "order" against a chaotic system is a mistake and destined for the same results as the mayors who built "projects" to "get rid of" the slums. If you don't change the basic conditions through emergence, you'll never win.
