Thus it was that Syrian and Russian forces began a new offensive in the northern province of Idlib last week, once again targeting civilians and, according to humanitarian aid groups, driving more than 100,000 people toward the border with Turkey. The attack is the resumption of a push into the province that began last April and displaced more than 500,000 people before an August cease-fire. Humanitarian aid groups say the current offensive could soon double that number, leaving tens of thousands of people living in the open in harsh winter conditions. Turkey long ago sealed its border with Syria, meaning the refugees have no safe place to go.
Idlib has long posed a complex problem for Turkey and Western governments. Its population of some 3 million people, including many thousands of refugees from other parts of Syria, is controlled by an extremist offshoot of al-Qaeda, Hayat Tahrir al-Sham. But the Syrian and Russian tactics for reconquering the province are aimed mostly at innocent civilians. According to the Syrian Observatory for Human Rights, more than 5,000 have been killed since April.
Turkey promised last year to disarm the extremists but, while it has set up its own military outposts in Idlib and backed other rebel forces, it has failed to deliver. This week, its diplomats once again were reduced to pleading with Russia to stop the offensive. The United States, which once did the bargaining with Moscow, has become an impotent observer. “Russia, Syria, and Iran are killing, or on their way to killing, thousands of innocent civilians in Idlib Province. Don’t do it!” President Trump tweeted Thursday. He responded to the last offensive with a similar tweet — and nothing else.
As Mr. Trump’s tweet indicated — “Turkey is working hard to stop this carnage” — President Recep Tayyip Erdogan has the best chance of preventing the looming humanitarian catastrophe. He seems to be trying: The Syrian Observatory for Human Rights reported that scores of Turkish military vehicles crossed into Syria on Wednesday night. The Turks, at best, could use diplomacy and reinforcement of their existing outposts to curtail the offensive, while doing more to neutralize extremist forces.
Still, it should be clear who is responsible for the latest wave of Syrian suffering: the Assad regime and Russian President Vladimir Putin. Congress recently approved new legislation sanctioning the Syrian government and all who do business with it, including Russia; legislators should insist that it be rigorously enforced.
