The terrorist group Al Qaeda so far is a movement, not a nation. In contrast, ISIS (the organization calling itself the Islamic State) holds territories in Syria and Iraq and has a land-based army. These and other distinctions were made by Audrey Kurth Cronin in his article “ISIS Is Not a Terrorist Group” (March/April 2015 Foreign Affairs).

Because ISIS is essentially a nation, some suggest a conventional war against it. Cronin calls this a “folly.” He reminds his readers: “Wars pursued at odds with political reality cannot be won.” Such a war would be exhausting and certainly not supported by the American public over a necessarily long duration.

Cronin advises a policy of containment, the policy generally followed in the Cold War with the Soviet Union. We never fought a hot war with the Soviet Union. We waited out our adversary until it collapsed. While waiting, we shored up allies and built our economy. We knew some colossal failures (Vietnam), but overall, our policy was correct.

Similarly, Cronin suggests that we become a “diplomatic superpower,” rather than one dependent solely on military solutions. Effective leadership requires patience.
