Paradoxically, Daniel Pipes believes, it could. As a result of the vicious civil war in Syria and Iraq, with the concomitant violent persecution of religious and ethnic minorities and the mass movement of refugees, the region seems to be reorganizing itself along more cleanly demarcated and hence more stable lines. Pipes explains:
Syria and Iraq have undergone strikingly similar developments. After the demise of monstrous dictators in 2000 and 2003, each has broken into the same three ethnic units: Shiite Arab, Sunni Arab, and Kurd. Tehran dominates both Shiite-oriented regimes, while several Sunni-majority states (Turkey, Saudi Arabia, UAE, Qatar) back the Sunni rebels. The Kurds have withdrawn from the Arab civil wars to build their own autonomous areas. . . .
In brief, Iraq and Syria are devolving into their constituent religious and ethnic parts; Lebanon is becoming more Sunni and Jordan less Palestinian. However gruesome the human cost of the Syrian civil war, its long-term impact potentially renders the Middle East a less combustible place.
