Middle East & North Africa

As NATO enters its 70th year of existence the challenges to Europe’s security are as much in flux as are the appropriate answers to deal with them. Moreover, the framework of dealing with European security has extended beyond the present members of NATO and the EU as former members of the Soviet Union struggle to become democracies whose fate has therefore become a concern to the West.

Iran has been a critical player in the Syrian war since 2011, crafting a complex foreign policy and military strategy to preserve its Syrian ally. What have been the drivers of Iranian decision-making in this conflict? And how has Iranian strategy evolved over the course of the war? This article argues that the logic of deterrence has been fundamental not just for shaping the contours of Iran–Syria relations since the Islamic Revolution of 1979, but also for determining the overall trajectory of Iranian strategy in the Syrian war. The authors outline Iran's decision-making calculus and divide the country's strategy on Syria after the Arab Spring into four primary phases: 1) a ‘Basij’ strategy to establish local militias in Syria; 2) a regionalization strategy to incorporate transnational fighters and militias in the war effort; 3) an internationalization strategy to incorporate Russia and balance the United States; and 4) a post-ISIS deterrence strategy to balance against the United States, Turkey and Israel. Iran's Syria strategy progressively escalated in response to the possible defeat of its ally and the deterioration of its forward deterrence capacities against the United States and Israel. Today, the potential for direct inter-state conflict is rising as proxy warfare declines and Iran attempts to maintain the credibility of its forward deterrence.

Confused messaging by the American government on Syria, with presidential tweets and dissonant statements from senior officials, has caused international whiplash in recent weeks. This hasty announcement and its botched implementation have already harmed American credibility and risk inflaming an already complex situation.

Even after Secretary of Defense Jim Mattis resigned over the decision, two of President Donald Trump’s top advisers have offered different messages about his intentions for a Syria withdrawal.

Events in the Middle East tend to have serious policy implications for the United States given the range of important U.S. economic, political, counterterrorism, and broader military interests in the region. Although there is a healthy debate to be had about where the Middle East might fit into a potential recalibration or rebalancing of U.S. global priorities, at this juncture I don’t believe it would be in U.S. interests to turn its back on the region’s crises and just hope for the best. 

Iran is primarily concerned with preserving Syria’s prominent role in the Axis of Resistance and its overarching goal of securing its regional deterrence. Accordingly, the collapse of Damascus was intolerable because it would have negatively affected Iran and its allies in the region. This includes securing supply routes to Lebanon; enhancing the deterrence capabilities and operational experience of the Axis of Resistance against Israel and the United States, especially with Trump’s renewed hostility; and balancing Turkey in northern Syria. In addition, preserving Syria’s significant position within the Axis of Resistance serves to showcase Iran’s effectiveness in supporting allies and in its leadership role in the axis.
