The United Nations says it has run out of words on Syria, but we, the undersigned, still have some for the governments, parliamentarians, electorates, and opinion leaders of the powers upon whom the international legal order has hitherto depended.

The world is a bystander to the carnage that has ravaged the lives of Syrians. All has happened in full view of a global audience that sees everything but refuses to act.

Through Russian obstruction and western irresolution, the UN Security Council has failed to protect Syrians. To the extent that it has been able to pass resolutions, they have proved ineffectual. All they have done is provide a fig leaf to an institution that appears moribund. Perhaps conscious of the stain this might leave on its legacy, the UN has even stopped counting Syria’s dead. After seven years, these nations appear united only in their apathy.

It will be redundant to list the nature and magnitude of all the crimes that the Assad regime has committed against Syrians, aided by local and foreign militias, by Iranian strategic and financial aid, by Russian airpower and mercenaries — and by international indifference. The world that watched and averted its eyes is its passive enabler.

Syrians were shot and killed in broad daylight for protesting injustice. They were imprisoned, tortured, and executed. They were bombed and shelled. They were besieged, raped, and humiliated. They were gassed. They were displaced and dispossessed.

Those with the power to act have been generous with expressions of sympathy but have offered nothing beyond the wish that this war on civilians — which they grotesquely call a “civil war”— would end. They call on “all parties” to show restraint, even though one side alone has a virtual monopoly on violence; they encourage all parties to negotiate, even though the opposition is entirely without leverage. They say there is “no military solution” though the regime has given no indication that it believes in a solution of any other kind. Meanwhile, pleas from aid agencies and endangered Syrians fall on deaf ears.

Refugees — the only Syrians to have received some assistance — have seen their plight depoliticized, isolated from the terror that forced them to flee.

Today, as Idlib and Afrin burn, the inevitable is unfolding in Ghouta, the huge open-air concentration camp about to enter its fifth year under siege. What happens next is predictable because the same formula has been applied repeatedly over the past seven years. After holding a civilian population hostage, blocking food, medicine, and aid of any kind, the regime bombs the area relentlessly, in particular its medical facilities, until it capitulates. Those who survive are then forced from their homes that are then expropriated for demographic engineering with the aim of creating politically homogeneous geographies.

While there are no longer any illusions about the role of the Security Council, every member state has nevertheless adopted and pledged to uphold the Responsibility to Protect (R2P) doctrine under the UN’s Office on Genocide Prevention. The destruction of Syria was preventable, and can now only be ended by the elected and appointed members of democratic bodies if they fulfill their obligations under R2P to protect Syria’s endangered population from war crimes, ethnic cleansing, and what UN war crimes investigators have themselves labeled the “crime of extermination.”

For the agony of the people of Syria to come to an end, this must be forcibly stopped. The perpetrators of these colossal crimes against humanity must be halted, once and for all. There are myriad geopolitical reasons why this is an imperative, but none as immediate and important as the sanctity of life and the exercise of free will. Inaction would reduce these principles to the status of platitudes devoid of all meaning. To their misfortune, Syrians dared to believe in these principles; they dared to believe that while their struggle for dignity was theirs alone, they wouldn’t be abandoned to such a fate in the twenty-first century.

Today, appealing once more to the ethics and the codes of moral conduct on which democracy and international law are built, we ask you to act now to stop the Syrian genocide: demand an immediate ceasefire, an immediate lifting of all sieges, immediate access for relief aid agencies, release of political detainees, and immediate protection for all Syrian lives.
