THE HAGUE NETHERLANDS – The international community’s failure to bring the Syrian civil war to an end is a tragedy — especially for the country’s long-suffering people. In one respect, multilateral action has had a clearly positive impact: the elimination of the Syrian government’s chemical weapons program. And yet there are persistent reports that chemical weapons, including sulfur mustard (commonly known as mustard gas) and chlorine bombs deployed against civilians, continue to be used in Syria.
The stakes could not be higher. The perpetrators of these attacks must be identified and brought to justice. Allowing the use of chemical weapons to go unpunished not only could reverse one of the few promising developments in the Syrian conflict; it also threatens to undermine international norms on the use of toxic gas and nerve agents, increasing the possibility that they will be used in terrorist attacks.
In August 2013, rockets containing deadly sarin gas struck Ghouta, a rebel-controlled suburb near Damascus. Horrific images of women and children dying in agony mobilized international consensus against the use of these types of weapons. In October 2013, following Syria’s accession to the Chemical Weapons Convention, a joint mission of the Organization for the Prohibition of Chemical Weapons (OPCW) and the United Nations was tasked with eliminating the country’s chemical arsenal and production facilities.
Less than a year later, the mission accomplished what no military intervention could have achieved; the strategic threat from Syria’s chemical weapons was effectively eliminated. Work to clarify certain aspects of the government’s initial declaration about its weapons program is ongoing; but 1,300 metric tons of chemical weapons, including sulfur mustard and precursors for deadly nerve agents, have been accounted for and destroyed under the watchful eyes of OPCW inspectors.
This achievement must not be allowed to be rolled back. The Chemical Weapons Convention is one of mankind’s most successful disarmament efforts. Since 1997, 192 countries have agreed to be bound by its provisions, and 91 percent of the world’s declared chemical weapons have been destroyed. The continued use of chemical weapons in the Syrian conflict is not only causing terrible suffering among the country’s civilian population; it also risks eroding the convention’s credibility.
A fact-finding mission established by the OPCW in April 2014 found “compelling confirmation” that a toxic chemical — most likely chlorine gas — was used “systematically and repeatedly” as a weapon in villages in northern Syria. It was on the basis of these findings that the U.N. Security Council agreed in August 2015 to create a joint investigative mechanism of the OPCW and the U.N. and task it with identifying those responsible for the use of chemical weapons in the conflict.
The fog of war can’t be allowed to create a fog of responsibility. The perpetrators of chemical attacks must be held to account, whoever they are. International investigators deployed in Syria bring vital expertise to this important mission. It is crucial that political leaders express confidence in their impartiality, allow them to carry out their work unobstructed, and not second-guess their conclusions. Once those responsible for the use of chemical weapons have been identified, the international community must ensure that they are prosecuted, in order to send a clear signal about the inviolability of the global ban.
Persistent allegations that nonstate actors are using chemical weapons in Syria and northern Iraq are of particular concern, as they raise the possibility of toxic chemicals being used in terrorist attacks. Manufacturing nerve agents is a complex process, but extremists can easily deploy toxic industrial chemicals — such as chlorine gas — if they have them in their possession. A conventional attack against a chemical facility is another potentially devastating risk — one that is not beyond the capabilities of a well-funded terrorist group.
Nearly two decades after the Chemical Weapons Convention entered into force, the treaty is facing a major test. The threat that toxic gas or nerve agents will be deployed in a conflict between countries has been all but eliminated. Failure to punish their use in the Syrian civil war risks undermining the regime that has brought us to the threshold of a chemical weapons-free world.
