Lee Harris points out the fatal flaw in the argument of the “non-interventionists“:

We may agree with Ron Paul that our interventionist policy in the Middle East has led to unintended negative consequences, including even 9/11, but this admission offers us absolutely no insight into what unintended consequences his preferred policy of non-intervention would have exposed us to. It is simply a myth to believe that only interventionism yields unintended consequence, since doing nothing at all may produce the same unexpected results. If American foreign policy had followed a course of strict non-interventionism, the world would certainly be different from what it is today; but there is no obvious reason to think that it would have been better.
