As Cohen knows, winning World War IV would require dropping many, many more bombs and invading, and then occupying for years to come, many more countries. After all, it’s not just ISIS that Washington will have to deal with, but also its affiliates, offshoots, wannabes, and the successors almost surely waiting in the wings. And don’t forget al-Qaeda.

Cohen believes that we have no alternative. Either we get serious about fighting World War IV the way it needs to be fought or darkness will envelop the land. He is undeterred by the evidence that the more deeply we insert our soldiers into the Greater Middle East the more concerted the resistance they face; that the more militants we kill the more we seem to create; that the inevitable, if unintended, killing of innocents only serves to strengthen the hand of the extremists. As he sees it, with everything we believe in riding on the outcome, we have no choice but to press on.

While listening carefully to Cohen’s call to arms, Americans should reflect on its implications. Wars change countries and people. Embracing his prescription for World War IV would change the United States in fundamental ways. It would radically expand the scope and reach of the national security state, which, of course, includes agencies beyond the military itself. It would divert vast quantities of wealth to nonproductive purposes. It would make the militarization of the American way of life, a legacy of prior world wars, irreversible. By sowing fear and fostering impossible expectations of perfect security, it would also compromise American freedom in the name of protecting it. The nation that decades from now might celebrate VT Day — victory over terrorism — will have become a different place, materially, politically, culturally, and morally.

In my view, Cohen’s World War IV is an invitation to collective suicide. Arguing that no alternative exists to open-ended war represents not hard-nosed realism, but the abdication of statecraft. Yet here’s the ultimate irony: even without the name, the United States has already embarked upon something akin to a world war, which now extends into the far reaches of the Islamic world and spreads further year by year.

Incrementally, bit by bit, this nameless war has already expanded the scope and reach of the national security apparatus. It is diverting vast quantities of wealth to nonproductive purposes even as it normalizes the continuing militarization of the American way of life. By sowing fear and fostering impossible expectations of perfect security, it is undermining American freedom in the name of protecting it, and doing so right before our eyes.

Cohen rightly decries the rudderless character of the policies that have guided the (mis)conduct of that war thus far. For that critique we owe him a considerable debt. But the real problem is the war itself and the conviction that only through war can America remain America.

For a rich and powerful nation to conclude that it has no choice but to engage in quasi-permanent armed conflict in the far reaches of the planet represents the height of folly. Power confers choice. As citizens, we must resist with all our might arguments that deny the existence of choice. Whether advanced forthrightly by Cohen or fecklessly by the militarily ignorant, such claims will only perpetuate the folly that has already lasted far too long.
