Closer Iran-Turkey Ties: Regional Implications and Significance for Israel

INSS Insight No. 974, September 27, 2017

עברית

President of Turkey Recep Tayyip Erdogan (R) shakes hands with General Staff of the Armed Forces of Iran, Mohammad Bagheri (L) ahead of their meeting at Presidential Complex in Ankara, Turkey on August 16, 2017.

After years of disagreement between Iran and Turkey, particularly regarding the war in Syria, there are many recent signs of an increase in cooperation between Tehran and Ankara. A range of developments on the ground, including the success of Iran and Russia in ensuring the continuation of the Assad regime; cooperation between the United States and the Kurds in the fight against the Islamic State; and concern about the consequences of Kurdish ambitions for independence, as well as Turkey’s decision to send armed forces to Syria to prevent this development have spurred the need for an Iranian-Turkish rapprochement and growing cooperation with Russia. This process, which is gaining momentum, does not serve the interests of Israel, and joins a range of issues that divide Jerusalem and Ankara: Turkey’s relations with Hamas, Turkish incitement against Israel during the escalation of tension around the Temple Mount, Turkey’s weak relations with Egypt, and its stance vis-à-vis Qatar in the crisis among Sunni Arab countries.


The past year has seen evidence of progress in the gradual rapprochement process between Turkey and Iran, and in the words of Iranian President Hassan Rouhani, "A new era of military and defense cooperation between our two countries has begun." Some of the most prominent examples of this rapprochement include the historic visit of the Iranian Chief of Staff to Ankara in August 2017, a first visit of this nature since the Islamic Revolution in 1979; the meeting of Presidents Rouhani and Recep Tayyip Erdogan during the Astana talks (September 9); and the agreement reached by the two leaders and Russia regarding the de-escalation zone around Idlib (September 16), for which these three are patrons and guarantors. In addition, Erdogan plans to visit Iran (on October 4). In the economic sphere, Iran, Turkey, and Russia have signed a three-way deal on oil and gas for drilling in Iran – an important matter for Turkey, which has no significant energy sources within its borders. This positive sentiment comes after years of tension regarding the war in Syria, where Iran has supported the Assad regime with fighters, supplies of weapons, and funding. While Turkey strongly supported the opposition factions fighting against Assad, Iran in effect has ensured the continuation of the regime.

Indeed, there is no doubt that the central factors underlying this rapprochement are the success of Russia and Iran to maintain the regime of Syrian President Bashar al-Assad, and the growing strength of the Syrian Kurds, which have led Turkey to acknowledge that it has no choice but to cooperate with the victorious Russian-Iranian axis in order to minimize the losses it incurred due to the civil war in Syria. Iran and Russia presumably feel the need to work with Turkey because of its potential to cause damage, as shown by its extensive support for the rebel forces in Syria – aid from which it has only recently partially retreated. Turkish attention is at present directed mainly toward the Kurdish issue, and specifically to the effort to ensure that the Kurds will be unable to set up an independent entity in northern Syria, particularly in view of their close military cooperation with the United States in the war against the Islamic State, which at present is focused on taking al-Raqqah. However, through the agreement reached in the Astana talks regarding Idlib, Turkey will acquire a status that will boost its position in Northern Syria beyond just the Kurdish issue.

In the Kurdish context, the shared interests of Turkey and Iran are also clear with respect to the decision and insistence of the President of the Kurdish Regional Government in Northern Iraq, Massoud Barzani, to hold a referendum on September 25, 2017 on the question of establishing an independent Kurdish state in Northern Iraq. This issue is very disturbing for neighboring countries, as well as the American government. Iran is strongly opposed to this move, because of the risk it poses of dividing Iraq as well as spilling over to the large Kurdish minority in Iran. This criticism was sounded, for example, during visits of the Quds Force commander, Qasem Soleimani, to Barzani. Turkey is also not happy with the referendum, particularly with the decision to hold it also in the disputed territories in Iraq, above all Kirkuk.

The expanding range of shared interests between Iran and Turkey includes the crisis in the Gulf since June 2017, when Saudi Arabia, the UAE, Bahrain, and Egypt cut off ties with Qatar and imposed an air and sea embargo. In this crisis, Turkey and Iran found themselves on the same side and have helped Qatar cope with the consequences. For Turkey, the alliance with Qatar is one of its few most stable relationships in recent years, and also has an ideological basis as a "Muslim Brotherhood axis" of sorts. Ankara's decision to set up a military base in Qatar and accelerate implementation of this decision following the Gulf crisis is striking evidence of the strength of the ties between these countries. In addition, Turkey believes that if the Gulf states and Egypt manage to defeat Qatar, it itself will be the next target for their hostile activities.

The new rapprochement between Turkey and Iran dovetails with the similar rapprochement between Turkey and Russia, which enabled the talks in Astana and Turkey's consequent involvement in the arrangement in Syria. This relationship was reinforced significantly following the declaration by Erdogan on September 11 that a down payment was made to Russia for implementation of the deal to purchase an S-400 air defense system – a deal that prompted tension in Turkey’s relations with the United States, which is opposed to this move. This joins the still open issue of Turkish assistance to bypass the sanctions imposed on Iran for its nuclear program. There was a recent salient development in this context when US federal prosecutors announced that a warrant had been issued for the arrest of former Turkish Finance Minister Zafer Caglayan on charges of being involved in bypassing the sanctions. The corruption and bribes involved in the "gold for oil" deals, through which Turkey helped Iran to evade some of the consequences of the banking sanctions, are also attributed to the Turkish President's close circle. Erdogan and the current Finance Minister responded strongly to the US decision to charge Caglayan.

The failed coup attempt in Turkey in July 2016, and the fear of another such attempt, has heightened the tension between Turkey and the United States. The most problematic issue is Turkey's request that Washington extradite the religious preacher Fethullah Gulen, who is suspected of being behind the failed attempt. In addition, there are problems with the West arising from requests for political asylum in Western countries by members of the Gulen movement, and cases of Western citizens arrested in Turkey on suspicion of involvement in the coup, arrests that from the outside appear arbitrary and baseless. These matters and the lobby activities around every such case cause ongoing tension in relations and create a space for Turkish-Iranian and Turkish-Russian rapprochement.

For Israel, apart from the deep conflicts that continue to cast a shadow on relations with Turkey, mainly in the Palestinian context, and above all Turkey's relations with Hamas and incitement against Israel during the al-Aqsa events, the developing ties between Ankara and Tehran add a serious issue to the differing agendas of the two countries. In fact, in most matters at the top of Israel's defense agenda – the future situation in Syria, particularly the continued Iranian presence there; relations with the Gulf states versus Qatar; relations with Egypt, which contrast with the prolonged crisis between Cairo and Ankara; and the tension with Iran on all issues – the two countries are currently on opposite sides. Moreover, while developments on the ground have forced Turkey in some cases to change its policy in ways that do not reflect deep convergence of interests with Iran, at present there is no significant meeting of Turkish and Israeli interests.

The intensity of the threat posed to Israel by the current cooperation between Turkey and Iran should not be exaggerated, since it clearly has its limits and there are still matters that divide Ankara and Tehran. Nevertheless, if Israel hoped that Turkey would share Jerusalem's concerns about Tehran and that these shared concerns could be leveraged, it appears that the current rapprochement between Turkey and Iran neutralizes this possibility, at least for the present.

The Second “Imposed War”: The Israel–Iran War and Its Implications for Iran’s National Security
The 12-day war between Iran and Israel in June 2025 marked the sharpest escalation to date in the ongoing confrontation between the two states. Despite its relatively short duration, the war had a destabilizing effect on the Islamic Republic due to the success of Israel’s opening strike, the decision of the United States to join the campaign, and the damage sustained by Iran’s critical strategic systems—notably its nuclear program and long-range missile arsenal. Since the end of the war, Iran has engaged in an ongoing process of drawing lessons from the serious gaps revealed in the Islamic Republic’s deterrence and defense capabilities. The Iranian leadership is certainly aware of the need for improvements and adjustments to its national security doctrine; yet for now, this does not appear sufficient to produce a fundamental shift in Iranian strategy. It seems that Iran prefers to make adjustments within the existing framework by finding acceptable solutions to the gaps exposed rather than introducing major changes to its overall strategy. In any event, the new reality in Iran created by the war is characterized by instability, and it is doubtful whether the current status quo can endure for long. This is exacerbated by the growing possibility of a miscalculation between Iran and Israel that would lead to renewed clashes, or high-risk decisions by Iran on both the nuclear issue and on the regional front. This memorandum seeks to examine the lessons that Iran is drawing from the war and its implications in four main areas: the nuclear program, strategic military systems, the regional arena, and the domestic arena—and to assess how the war has influenced Iran’s national security concept. In addition, it includes a set of policy recommendations intended to block, or at least delay, Iran’s efforts to rebuild its strategic capabilities, foremost among them the nuclear program, and the pro-Iranian axis in the region, and to reduce as much as possible the risk of renewed fighting.

Aircraft Under the Radar: Mechanisms of Evading Sanctions in Iran’s Aviation Sector
Despite being subjected to one of the harshest sanctions regimes in the world, Iran has succeeded in building a sophisticated, law-evading mechanism to support its aviation industry, which reflects the broader principles of the shadow economy it has developed. This article maps the operational architecture of that mechanism, based on using front and shell companies in countries with little transparency, layered ownership registries, bursts of activity designed to complete transfers within short timeframes, and flight-path planning that includes fictitious emergency landings to allow aircraft to quietly enter Iran. The article describes how Iran’s aviation sector—significantly harmed by sanctions—has shifted from a civilian transportation tool to a core component of the regime’s economic and security strategy, enabling it to continue functioning, finance its regional proxies, and project resilience in the face of international pressure. The aviation industry represents only one link in a much larger apparatus designed to evade sanctions in the trade of oil, gold, and dual-use technologies; yet the aviation sector clearly demonstrates the method: a sophisticated integration of state, market, and underground networks that operate in regulatory gray zones and disrupt efforts to globally enforce the sanctions.
