Putin firmly opposes U.S. policy toward Syria and the threat of force against Iran. But his opposition stems neither from anti-Americanism nor a desire to back the Iranian mullahs or Syria's Bashar al-Assad in their struggles with the West. It is rooted in his obsession with stability. Helping Tehran secure a nuclear weapon and keeping Assad in Damascus are not Putin's goals. But an Israeli or U.S. attack on Iran's nuclear sites, and NATO or the United Nations intervening in Syria to forcibly remove Assad, would increase global volatility.
