The Causes of Terrorism

There's been a bit of discussion lately, again, about the causes of terrorism. We discussed in in PIS two weeks ago and one member came up with the very interesting observation that the London suicide bombers might be analogous to high school shooters. There's something in that, I think. Anyway, for some more discussion:

• A short post with a long discussion at Ari's blog
  
• Two somewhat longer posts (1, 2) at my blog
  
• A post on Iraq at John's blog which deals with some of the issues

Feel free to continue the discussion here.
