I don't think you can lump the Gulf Arabs and the Turks in with the Russians and Iranians, the latter have provided intermittent support to those fighting Assad's genocide, while the latter have facilitated it, but the rest is to the point.
"Some two years ago, a senior White House official told visitors from Capitol Hill that there were no attractive parties in Syria: that there was merit in simply allowing the fire consuming the country to burn itself out. That civilians—many of them women and children—would be disproportionately incinerated in the resulting inferno seems not to have struck the official as morally relevant or policy pertinent. Yet now, as reports of regime shakiness begin to accumulate, some additional practical, policy consequences of having done virtually nothing to protect Syrian civilians from an Assad regime campaign of mass homicide come into focus.
To put the matter succinctly, the willingness of the Obama administration to make do with moralistic rhetoric about Assad regime war crimes and crimes against humanity has led it to an astounding analytical conclusion: he who has authorized acts of mass homicide on a daily basis—Bashar al-Assad—ought not be removed from power too quickly lest Islamist rebels take Damascus and conduct massacres in communities involuntarily implicated by regime criminality. The barrel bombing, starvation sieges, chemical attacks, and door-to-door atrocities have been so widespread, so intense, and so unopposed by a hollowed-out West that now the specter of additional mass atrocities—perhaps genocide—transcending Arab Sunni Muslims presents itself.
President Barack Obama continues to insist that the only alternative to leaving people utterly unprotected—the alternative he insists his critics favor—would have been the invasion and occupation of Syria. The President has misleadingly made it a matter of all or nothing, thereby justifying his choice of nothing.
Whatever use a straw man argument might have as a here-and-now excuse for inaction or as an alibi for future historians, it fails the test of truth telling. No one has advocated invading and occupying Syria. Even the most dedicated advocates of protecting human beings from mass murder have not recommended such a step. Ways and means that are much more modest are available to an administration willing to transcend talk and do actual things. Examples abound.
Is there a diplomatic strategy aimed specifically at persuading Tehran and Moscow to pressure their client into abandoning mass homicide? Has President Obama wrung from his military advisors every conceivable option—short of invasion and occupation, and even short of bombing airfields—to stop (or at least complicate) the barrel bombing and (if necessary) neutralize possible mass murder alternatives such as Scud missiles and field artillery trained on residential neighborhoods? Is there an ongoing diplomatic offensive aimed at binding regional partners to the creation of safe havens inside Syria? Is there a move afoot to transcend an anemic train-and-equip program by creating an all-Syrian national stabilization force capable of protecting Syrian civilians? If patriotic Syrians cannot find ways to overcome their divisions and unite against both Iran and ISIL while themselves pledging to protect civilians, they will lose their country forever. If Iranians, Russians, Turks, and Gulf Arabs see civilian vulnerability merely as an inevitable cost of doing business, Syrians should rise up against the lot of them.
Giving the protection of Syrian civilians operational priority as opposed to lip service can save lives, build a foundation for political conflict resolution, and prevent ongoing mass homicide from assuming the additional dimension of genocide. Yet it will take more than words. It will take this President changing course. For as bad as Syria and its neighborhood are today, they can be immeasurably worse twenty months from now."
