Rep. Pete Hoekstra made a very insightful observation about al-Qaeda on ThisWeek. “They haven’t set as a criteria that they have to do something as big as 9/11,” he told Terry Moran. Instead, they’re “satisfied with the kind of successes that they saw at Fort Hood and what they anticipated would happen on Christmas day.”

Unfortunately, it fell to Michael Chertoff on Meet The Press to draw out the implications of Hoekstra’s insight. Asked if Umar Farouk Abdulmutallab’s ambitions to blow up a plane — and not, say, to use it as a missile — represent diminished al-Qaeda’s capabilities, Chertoff replied, “I think that’s exactly right.” He continued, “As troubling as this incident is, on occasion after occasion we’ve disrupted plots… [al-Qaeda is] actually being forced to work under a great deal of pressure and are handicapped at carrying out these types of plots.”

And they’re right! It’s OK to admit that al-Qaeda’s capabilities are eroding as ours are improving! Shout it from the heavens! There’s something twisted about the political convention that it represents weakness to say that they’ve been boxed in — it suggests that we should be fighting forever, and that counterterrorism success boils down to an invocation that we should just keep fighting. There are some people, secure in Washington, for whom counterterrorism and national security is a hopelessly meta issue, measured exclusively in preening, posturing and rhetoric.
