A wake-up call to Syrian chemical atrocities

We should pay heed to the Organization for the Prohibition of Chemical Weapons finding on Wednesday that Syrian President Bashar Assad used chemical weapons against three civilian targets in 2017.

This is a wake-up call. Assad continues to retain chemical weapons stocks, delivery systems, and the strategic rationale for using them. He will use them again if allowed to believe, as he does now, that he can do so without significant cost.
