Mueller's book is likely to be one of many interesting books on terrorism that I simply won't have time to read. A few weeks ago I blogged about his views in two different posts here and here. Those posts will first take you to an article that Mr. Mueller wrote for Foreign Affairs and then to a roundtable discussion of his views.
Jonathan Rauch discusses James Bowman's Honor: A History, focussing on how the concept of honor can be used to understand terrorism and the politics of the Middle East.
Two year ago I posted a very critical response to something that Bowman wrote in response to the NEA study Reading at Risk. Since then I've regarded him as little more than a right-wing hack. But Rauch's article clearly indicates that Bowman's book is worth reading, and since I respect Rauch, I should relent and give Bowman a second chance.
In short, Mueller argues that if al-Qaeda wanted to strike the United States in some fashion, it could have done so fairly easily by now. So the absence of an attack is an indication that there are no foreign terrorists in the United States, and that they aren't inclined (or perhaps aren't able) to make their way here to carry out attacks.
