Michael Gordon writing for the NYT attempts to get inside the head(s) of terrorists. An interesting hypothesis.

Does Mr. Gordon's notion have any basis in reality? I think that the honest answer is that no one outside of the terrorist community and possibly the intelligence communities can say with any level of certainty.

His simple idea has great appeal as a reason behind the Spanish bombings. However, that does not make it any more real.

Give it a read, and ponder.
