Sulaimaniya, Iraq — Being back in Iraq after two years’ absence has helped me to put my finger on the central question bedeviling U.S. foreign policy in the Middle East today: What do you do when the necessary is impossible, but the impossible is impossible to ignore — and your key allies are also impossible?

Crushing the Islamic State, or ISIS, is necessary for stabilizing Iraq and Syria, but it is impossible as long as Shiites and Sunnis there refuse to truly share power, and yet ignoring the ISIS cancer and its ability to metastasize is impossible as well. See: Belgium.

And if all that isn’t impossible enough, our trying to make Iraq safe for democracy is requiring us to turn a blind eye to the fact that our most important NATO “ally” in the region, Turkey, is being converted from a democracy into a dictatorship by its president, Recep Tayyip Erdogan, who should now be called “Sultan Erdogan” for the way he is closing opposition newspapers and putting journalists on trial. But because we need Turkey’s air bases and cooperation to foster a modicum of democracy in Iraq tomorrow, we are silent on Erdogan destroying democracy in Turkey today. Go figure.

And to think that in America we have all these people competing to become president to get a chance to take responsibility for this problem! Has no one told them this is absolutely the worst time in 70 years to be managing U.S. foreign policy?

Obama has my sympathies. If you think there is a simple answer to this problem, you ought to come out here for a week. Just trying to figure out the differences among the Kurdish parties and militias in Syria and Iraq — the Y.P.G., P.Y.D., P.U.K., K.D.P. and P.K.K. — took me a day.

Let’s go back to the future of Iraq. “The problem in Iraq is not ISIS,” Najmaldin Karim, the wise governor of Kirkuk Province, which is partly occupied by ISIS, remarked to me. “ISIS is the symptom of mismanagement and sectarianism.” So even if ISIS is evicted from its stronghold in Mosul, he noted, if the infighting and mismanagement in Baghdad and sectarian tensions between Shiites and Sunnis are not diffused, “the situation in Iraq could be even worse after” ISIS is toppled.

Thank heavens for technology which is greatly diminishing our dependence on Middle Eastern oil.  Much of this troubled region is destroying itself and if it had happened a little more than a decade earlier, the potential consequences for the global economy would have been much worse.
