Citadel of Aleppo, Syria

The debacle that is U.S. Syria policy is today on naked display.

NATO ally Turkey and U.S.-backed Arab rebels this weekend attacked our most effective allies against ISIS, the Syrian Kurds.

Earlier in August, U.S. planes threatened to shoot down Syrian planes over Hasakeh, and our Iraq-Syria war commander, Lt. Gen. Stephen Townsend, issued a warning to Syria and Russia against any further air strikes around the city.

Who authorized Gen. Townsend to threaten to shoot down Syrian or Russian planes—in Syria?

When did Congress authorize an American war in Syria? Is the Constitution now inoperative?

That we are sinking into a civil war where we sometimes seem to be fighting both sides is a tribute to the fecklessness of the Barack Obama-John Kerry foreign policy and the abdication of a Congress that refuses to either name our real enemy or authorize our deepening involvement.

Our Congress appears again to have abdicated its war powers.

Consider the forces that have turned Syria into a charnel house with 400,000 dead and millions injured, maimed and uprooted.

On the one side there is the regime of Bashar Assad and its allies—Hezbollah, Iran and Russia. Damascus buys its weapons from Moscow and has granted Russia its sole naval base in the Mediterranean. And Vladimir Putin protects his interests and stands by his friends.

To Iran, the Alawite regime of Assad is a strategic link in the Shia crescent that runs from Tehran to Baghdad to Damascus to South Beirut and Lebanon’s border with Israel.

If Syria falls to Sunni rebels, Islamist or democratic, that would mean a strategic loss for Russia, Iran and Hezbollah, which is why all have invested so much time, blood and treasure in this war.

If they are going to lose Syria, Assad, Iran, Hezbollah and the Russians are probably going to go down fighting. And should we decide to fight a war to take them down, we would find ourselves with such de facto allies as ISIS and the al-Nusra Front, an affiliate of al-Qaida.

Have the hawks who want us to target Assad considered this?

The American people would never sustain such a war in the company of such allies, with its risks of escalation, to remove Assad, who, whatever we think of him, never terrorized Americans or threatened U.S. vital interests.

Years ago, Assad dismissed Obama’s demand that he surrender power, then defied Obama’s “red line” against the use of chemical weapons. He is not going to depart because some U.S. president tells him he must go.

As for the Syrian Kurds, the YPG, they have sealed much of the border with Turkey and fought their way ever closer to Raqqa, the capital of the ISIS caliphate. But what has elated the Americans has alarmed the Turks.

For the YPG not only drove ISIS out of the border towns all the way to the Euphrates; this summer, with U.S. backing, they crossed the river and seized Manbij.

Turkey’s fear is that the Syrian Kurds will link their cantons east of the Euphrates with their canton west of the river and create a statelet that could give Turkey’s Kurds a privileged sanctuary from which to pursue their 30-year struggle for independence.

If, when the war ends in Syria, the YPG is occupying all the borderlands, Ankara faces a long-term existential threat of dismemberment.
