I think John Mueller's "False Sense of Insecurity" argument about terrorism goes two far in a couple of respects, but it's mostly correct and overwhelmingly provides a crucial counterbalance to the tendency toward alarmism that's overtaken the country in recent years. Thus, it's great to see that he's written the lead essay for the 9/11 anniversary edition of Cato Unbound. The specific argument he makes in this new piece I agree with more-or-less entirely.
