Maureen Dowd, winner of the 1999 Pulitzer Prize for distinguished commentary, became a columnist on The New York Times Op-Ed page in 1995 after having served as a correspondent in the paper’s Washington bureau since 1986. She has covered four presidential campaigns and served as White House correspondent. She also wrote a column, "On Washington," for The New York Times Magazine. Ms. Dowd joined The New York Times as a metropolitan reporter in 1983. She began her career in 1974 as an editorial assistant for The Washington Star, where she later became a sports columnist, metropolitan reporter and feature writer. When the Star closed in 1981, she went to Time magazine.

Born in Washington D.C., Ms. Dowd received a B.A. degree in English literature from Catholic University (Washington, D.C.) in 1973. Ross Douthat joined The New York Times as an Op-Ed columnist in April 2009. Previously, he was a senior editor at the Atlantic and a blogger for theatlantic.com. His most recent book is “Bad Religion: How We Became a Nation of Heretics” (Free Press, 2012). He is also the author of “Privilege: Harvard and the Education of the Ruling Class” (Hyperion, 2005) and the co-author, with Reihan Salam, of “Grand New Party: How Republicans Can Win the Working Class and Save the American Dream” (Doubleday, 2008). He is the film critic for National Review. A native of New Haven, Conn., he now lives in Washington, D.C. ACROSS years of war and at an extraordinary cost, the United States built an army that was supposed to prevent jihadists from gaining a sanctuary in the heart of the Middle East. It had American-trained leaders, American-made weaponry and 250,000 men under arms . far more troops and firepower than any insurgent force that might emerge to challenge it. That army was the Iraqi Army, and we know what happened next: The Syrian civil war spilled over into Iraq, jihadists first found a foothold and then led an insurgency against the Iraqi military, and the jihadists won. American-organized units were routed; American-trained soldiers fled; American-made weapons fell into the hands of the Islamic State, the self-declared caliphate with which we ourselves are now at war.

Perhaps, just perhaps, there might be a lesson here about how hard it is to conjure up reliable allies amid the chaos of the current Middle East. But if so, we seem determined not to learn it, since our official strategy for fighting the Islamic State involves basically trying the same thing again, this time on the cheap: inventing allies, funneling them money and weaponry, and telling ourselves that it will all work out.

Those allies are the “moderate” and “vetted” . euphemisms for “not as scary as the other guys” . rebels in Syria, whom Congress voted last week to finance and train and arm. As fighting forces go, they promise to be rather less impressive than the last army we trained, since if all goes well just 5,000 rebels will be ready for the fight this year, or about one-sixth as many fighters as ISIS now has under arms. (And those odds get even longer when you consider that the rebels intend to use our weapons to fight the Assad regime as well.)If our failure to build an army capable of stabilizing Iraq after our departure looks like a pure tragedy, then the arm-the-rebels gambit in Syria has more than a whiff of farce. But really it’s a studied evasion, a way for this administration to pretend that we don’t face a set of deeply unpleasant options in our quest to contain or crush the caliphate.

The first realistic, non-farcical option is the one that the president seemed to choose initially, when he launched limited airstrikes to rescue the embattled Kurds last month. This would basically be a strategy of containment and attrition, oriented around the current lines of battle in Iraq, in which we see if the Kurds and those Iraqi Army units that didn’t collapse can push the front westward, see if a post-Maliki government can woo local Sunni leaders, and use our air power to degrade the caliphate’s fighting capacity while letting its internal weaknesses degrade it from within.

The trouble with containment is that it would leave the Islamic State in control of a great deal of territory (with more beheading videos, no doubt) for months and years to come. Hence the administration’s pivot to Syria; hence the strategic dream palace that is our arm-the-rebels strategy.

The cold reality, though, is that defeating ISIS outright in Syria will take something more substantial than dropping a few bombs in support of a few U.S.-trained moderates. Either the American military will have to intervene in force (including with substantial ground troops) or we’ll have to ally, in a very un-American display of machtpolitik, with Bashar al-Assad. Both options may have supporters within the Republican Party. Many hawks seem ready to send in ground forces, and John McCain has explicitly argued that we should be willing to go to war with both Assad and the Islamists at once. From Rand Paul, meanwhile, you hear what sounds like a version of the ally-with-Assad approach, albeit couched in somewhat ambiguous terms.

The White House would clearly prefer not to choose either path, either escalation. But its current approach seems likely to drift more in McCain’s direction, with a gradual ramping-up (today bombing, tomorrow special forces, the next day ... ?) in Syria that makes a clash with Assad and a multifront war steadily more plausible.

There is still time for the president to reconsider, to fall back on the containment-and-attrition strategy in Iraq and avoid a major commitment inside Syria. That strategy does not promise the satisfaction of the Islamic State’s immediate elimination. But neither does it require magically summoning up a reliable ally amid Syrian civil strife, making a deal with the region’s bloodiest dictator, or returning once again to ground warfare and nation-building in a region where our efforts have so often been in vain.

It does not traffic, in other words, in the fond illusions that we took with us into Iraq in 2003, and that hard experience should have disabused us of by now.

But some illusions are apparently just too powerful for America to shake.
