It seems particularly appropriate, on this 13th anniversary of the 9/11 attacks, to ponder anew what counterterrorism steps are prudent and effective, and what measures are reckless and counterproductive.

With this in mind, I was moderately inclined to go along with President Obama’s plan to attack the Islamic State in Iraq and Syria (ISIS), provided that he defined a limited and achievable set of goals, and therefore established limits on the size and scope of the U.S. military mission.

But when the president says this:

“We will hunt down terrorists who threaten our country, wherever they are.” 

I hear this:

“All that we have to do is to send two mujahedeen to the furthest point east to raise a piece of cloth on which is written al Qaeda, in order to make generals race there to cause America to suffer human, economic and political losses without their achieving anything of note…”

Though they didn’t race there, a team of U.S. special forces eventually made their way to Pakistan and pumped a couple of bullets into bin Laden, so he’s not making these videos any more. That seems worthy. If we can repeat these sorts of operations elsewhere, and shut up a few more loudmouths, we should.

But the larger point stands. We shouldn’t terrorize ourselves. We shouldn’t exaggerate the threat posed by terrorism. And we shouldn’t react in ways that feed the terrorists’ narrative, or serve the terrorists’ goals.
