Assume that the hawks get their way — that the United States does whatever it takes militarily to confront and destroy ISIS. Then what?

Answering that question requires taking seriously the outcomes of other recent U.S. interventions in the Greater Middle East. In 1991, when the first President Bush ejected Saddam Hussein’s army from Kuwait, Americans rejoiced, believing that they had won a decisive victory. A decade later, the younger Bush seemingly outdid his father by toppling the Taliban in Afghanistan and then making short work of Saddam himself — a liberation twofer achieved in less time than it takes Americans to choose a president. After the passage of another decade, Barack Obama got into the liberation act, overthrowing the Libyan dictator Muammar Gaddafi in what appeared to be a tidy air intervention with a clean outcome. As Secretary of State Hillary Clinton memorably put it, “We came, we saw, he died.” End of story.

In fact, subsequent events in each case mocked early claims of success or outright victory. Unanticipated consequences and complications abounded. “Liberation” turned out to be a prelude to chronic violence and upheaval.

Indeed, the very existence of the Islamic State (ISIS) today renders a definitive verdict on the Iraq wars over which the Presidents Bush presided, each abetted by a Democratic successor. A de facto collaboration of four successive administrations succeeded in reducing Iraq to what it is today: a dysfunctional quasi-state unable to control its borders or territory while serving as a magnet and inspiration for terrorists.

The United States bears a profound moral responsibility for having made such a hash of things there. Were it not for the reckless American decision to invade and occupy a nation that, whatever its crimes, had nothing to do with 9/11, the Islamic State would not exist. Per the famous Pottery Barn Ruleattributed to former Secretary of State Colin Powell, having smashed Iraq to bits a decade ago, we can now hardly deny owning ISIS.

That the United States possesses sufficient military power to make short work of that “caliphate” is also the case. True, in both Syria and Iraq the Islamic State has demonstrated a disturbing ability to capture and hold large stretches of desert, along with several population centers. It has, however, achieved these successes against poorly motivated local forces of, at best, indifferent quality.

In that regard, the glibly bellicose editor of the Weekly Standard, William Kristol, is surely correct in suggesting that a well-armed contingent of 50,000 U.S. troops, supported by ample quantities of air power, would make mincemeat of ISIS in a toe-to-toe contest. Liberation of the various ISIS strongholds like Fallujah and Mosul in Iraq and Palmyra and Raqqa, its “capital,” in Syria would undoubtedly follow in short order.

In the wake of the recent attacks in Paris, the American mood is strongly trending in favor of this sort of escalation. Just about anyone who is anyone — the current occupant of the Oval Office partially excepted — favors intensifying the U.S. military campaign against ISIS. And why not? What could possibly go wrong? As Kristol puts it, “I don’t think there’s much in the way of unanticipated side effects that are going to be bad there.”

It’s an alluring prospect. In the face of a sustained assault by the greatest military the world has ever seen, ISIS foolishly (and therefore improbably) chooses to make an Alamo-like stand. Whammo! We win. They lose.Mission accomplished.

Of course, that phrase recalls the euphoric early reactions to Operations Desert Storm in 1991, Enduring Freedom in 2001, Iraqi Freedom in 2003, and Odyssey Dawn, the Libyan intervention of 2011. Time and again the unanticipated side effects of U.S. military action turned out to be very bad indeed. In Kabul, Baghdad, or Tripoli, the Alamo fell, but the enemy dispersed or reinvented itself and the conflict continued. Assurances offered by Kristol that this time things will surely be different deserve to be taken with more than a grain of salt. Pass the whole shaker.
