When the civil war in Syria began in 2011, the U.S.-led bloc and its regional allies, including Saudi Arabia, devoted their resources to removing Syrian President Bashar al-Assad. However, as the result of Iranian-Russian cooperation to buttress the Assad’s government, they failed to achieve their goals. The addition to this alliance of Turkey, which initially opposed Assad’s government, has further made it clear that President Assad has won the six-year war and will remain in power. If successful, the trilateral cooperation can play a more substantive role in managing other crises in the region.
