The militants are bad people and this is bad news. But the more difficult question is, what should we-the outside world-do about it? That we are utterly opposed to such people, and their ideas and practices, is obvious. But how exactly should we oppose them? In Pakistan and Afghanistan, we have done so in large measure by attacking them-directly with Western troops and Predator strikes, and indirectly in alliance with Pakistani and Afghan forces. Is the answer to pour in more of our troops, train more Afghan soldiers, ask that the Pakistani military deploy more battalions, and expand the Predator program to hit more of the bad guys? Perhaps-in some cases, emphatically yes-but I think it’s also worth stepping back and trying to understand the phenomenon of Islamic radicalism.
