(CNN)The Saudi strategy does not seem to be working. The war in Yemen has turned into a disaster, creating a failed state on Saudi Arabia's border that is seething with anger against Riyadh. Qatar has not surrendered and doesn't seem likely to anytime soon. So far, the Shiites in Lebanon have acted responsibly, refusing to take the bait and plunge the country into civil war. But everywhere in the Middle East, tensions are rising, sectarianism is gaining ground and, with a couple of miscalculations or accidents, things could spiral out of control. With Trump so firmly supporting the Saudi strategy, the United States could find itself dragged further into the deepening Middle East morass.
