Citadel of Aleppo, Syria

After recent terrorist attacks on his country, Turkish President Recep Tayyip Erdogan recognizes that ISIS is a monster with which he cannot live. Thus, this weekend, he sent tanks and Arab troops to drive ISIS out of the Syrian border town of Jarablus.

Now Turkish troops and their Arab allies are moving further south into Syria to expel the Kurds from Manbij. Joe Biden, visiting Turkey, told the Kurds to get out of Manbij and back across the river.

How does the U.S. protect its interests while avoiding a deeper involvement in this war?

First, recognize that ISIS and the al-Nusra Front are our primary enemies in Syria, not Assad or Russia. Geostrategists may be appalled, but the Donald may have gotten it right. If the Russians are willing to fight to crush ISIS, to save Assad, be our guest.

Second, oppose any removal of Assad unless and until we are certain he will not be replaced by an Islamist regime.

Third, we should assure the Turks we will keep the Kurds east of the Euphrates and not support any Kurdish nation-state that involves any secession from Turkey.

America’s best and wisest course is to stop this slaughter that is killing a thousand Syrians a week, use our forces in concert with any and all allies to annihilate the Nusra Front and ISIS, keep the Kurds and Turks apart, effect a truce if we can, and then get out. It’s not our war.
