Nuclear negotiations between the P5+1 and Iran are currently facing congressional challenges and Israeli obstructionism. If the administration of U.S. President Barack Obama can withstand these pressures and reach a deal that leads to a détente between the U.S. and Iran, it will have implications for the regional balance of power as well as the ongoing conflicts in Syria and Iraq. As Turkey borders both of these countries and has a multitude of strategic and security interests regarding the nuclear negotiations, Turkish foreign policy will be impacted by Iran's approach to Iraq and especially Syria.
Turkey has had a simultaneously competitive and cooperative relationship with Iran. For the past several years, Turkey and Iran have compartmentalized their disagreement over Syria for the sake of mutual energy interests. A potential nuclear deal could benefit Turkey through the reduction of regional tensions as well as increased bilateral trade. However, the Turkish-Iranian disagreement over Syria will not be easily overcome even if a deal is reached because Iran is unlikely to shy away from its regional ambitions as a result. If anything, a détente might embolden Iran in knowing that it will not be threatened militarily by the United States. At the same time, Iran may modify its threat perception and rethink its regional foreign policy posture in order to reduce the cost of investing in the regime of Syrian President Bashar Assad. If the latter becomes the case, Iran and Turkey may be able to reduce their differences over Syria, contributing to stability in the region in the long run.
The reaction of regional actors toward a potential deal will have a bearing on the actual benefits. Saudi Arabia will be unhappy as it sees itself in an existential struggle to counter Iran throughout the region. Only an Iranian effort to reach out to Saudi Arabia and change its policy in Syria and Iraq would ease the Saudis' concerns, albeit to a limited extent. If the Saudi fears about Iran linger and Tehran does nothing to alleviate them in concrete terms, a nuclear deal may simply deepen their insecurity, as they would feel abandoned by the U.S. Continued Saudi-Iranian confrontation in the region would only worsen the prospects for a solution in Iraq and Syria.
Israel's reaction to a potential deal will predictably be based on a "no deal is better than a bad deal" framework. Israeli Prime Minister Benjamin Netanyahu has been pressuring the Obama administration to demand harsher terms in the negotiations, and he will almost certainly oppose any kind of deal that allows Iran to retain its nuclear enrichment capabilities. The Obama administration has been pushing back against Israeli criticism by calling Netanyahu names in a not-so-diplomatic way, which also speaks to the administration's anxiety about the potential for failure. It remains uncertain whether the deal will be acceptable to the newly Republican-dominated U.S. Congress or to Iranian Supreme Leader Ali Khamenei. Nevertheless, Israeli discontent over a possible deal will only add to regional tensions.
In addition to bolstering Obama's non-proliferation agenda, a potential deal will have implications for Iran's standing in the region. In 2010, Turkey, as a non-permanent member of the U.N. Security Council at the time, tried to help forge an agreement between the P5+1 and Iran. The Tehran Declaration was meant to be a confidence-building measure, but it was dismissed by the West based on the view that the agreement was part of an Iranian ploy to duck the impending sanctions resolution. Turkey's efforts in 2010 were driven by its desire to engage with Iran and help integrate it into the international system. Its insistence on diplomacy as opposed to sanctions was motivated by Turkey's interest in reducing regional tensions to allow for a stable and peaceful environment to pursue its business interests. These interests remain unchanged today and they can be the primary driver of cooperation with Iran.
