What's the biggest threat to world peace right now? Despite the horror, it's not chemical weapons in Syria. It's not even, for the moment, an Iranian nuclear weapon. Instead, it's the possibility of a wave of sectarian strife building across the Middle East.
The Syrian civil conflict is both a proxy war and a combustion point for spreading waves of violence. This didn't start out as a religious war. But both Sunni and Shiite power players are seizing on religious symbols and sowing sectarian passions that are rippling across the region. The Saudi and Iranian powers hover in the background fueling each side.
As the death toll in Syria rises to Rwanda-like proportions, images of mass killings draw holy warriors from countries near and far. The radical groups are the most effective fighters and control the tempo of events. The Syrian opposition groups are themselves split violently along sectarian lines so that the country seems to face a choice between anarchy and atrocity.
Meanwhile, the strife appears to be spreading. Sunni-Shiite violence in Iraq is spiking upward. Reports in the New York Times and elsewhere have said that many Iraqis fear their country is sliding back to the worst of the chaos experienced in the past decade. Even Turkey, Pakistan, Bahrain and Kuwait could be infected.
"It could become a regional religious war similar to that witnessed in Iraq 2006-2008, but far wider and without the moderating influence of American forces," wrote Gary Grappo, a retired senior Foreign Service officer with long experience in the region.
"It has become clear over the last year that the upheavals in the Islamic and Arab world have become a clash within a civilization rather than a clash between civilizations," Anthony Cordesman of the Center for Strategic and International Studies wrote recently. "The Sunni versus Alawite civil war in Syria is increasingly interacting with the Sunni versus Shiite tensions in the Gulf that are edging Iraq back towards civil war."
Some experts even say that we are seeing the emergence of a single big conflict that could be part of a generation-long devolution, which could end up toppling regimes and redrawing the national borders that were established after World War I. The forces ripping people into polarized groups seem stronger than the forces bringing them together.
It is pretty clear that the recent U.S. strategy of light-footprint withdrawal and nation-building at home has not helped matters. The United States could have left more troops in Iraq and tamped down violence there. We could have intervened in Syria back when there was still something to be done and some reasonable opposition to mold. At this late hour, one question is whether the sectarian fire has grown so hot that it is beyond taming. The second question is whether the United States has any strategy to limit the conflagration. Right now, President Barack Obama is focused on the imminent strike against the Assad regime, to establish U.S. credibility when it sets red lines and reinforce the norm that poison gas is not acceptable.
But the president does have the makings of a broader anti-sectarian strategy. He has at least three approaches on the table. The first is containment: trying to keep each nation's civil strife contained within its own borders. The second is reconciliation: looking for diplomatic opportunities to bring the Sunni axis, led by the Saudis, toward some rapprochement with the Shiite axis, led by Iran. So far, there have been few diplomatic opportunities to do this.
