Ankara accuses Tehran of betrayal: Is the alliance of convenience collapsing? 

ANKARA: Recent developments on the ground in Syria may be proof of the demise of the already fragile partnership between Turkey and Iran, the two guarantor states of the Astana process alongside with Russia. On Monday, Iranian Foreign Ministry spokesman Abbas Mousavi announced that Iran rejected any move from Turkey to establish military posts inside Syria, and emphasized that the integrity of Tehran’s key regional ally should be respected.
Prior to departing for Sochi, to meet with his Russian counterpart Vladimir Putin, President Recep Tayyip Erdogan said: “I condemn Iran’s stance on Operation Peace Spring. Unfortunately, there are splintering voices rising from Iran. This situation disturbs my colleagues and myself.”
Erdogan also accused Iran of betraying the consensus between the two countries, after Tehran condemned Turkey’s ongoing operation in northern Syria against Syrian Kurdish forces and demanded “an immediate stop to the attacks and the exit of the Turkish military from Syrian territory.”
The statements are considered by experts another sign that the alliance of convenience between the two regional competitors is ending, with their regional interests beginning to conflict.
Iran has always been a close ally of Syrian President Bashar Assad, and has been keen to engage Syrian Kurds, Assad’s government and Turkey in dialogue following Ankara’s offensive into northern Syria, within the framework of the Adana Agreement as a legal framework to establish security along the border.
Tehran also held surprise military drills near the Turkish border on the same day Turkey launched its operation into northern Syria.
Dr. Michael Tanchum, senior fellow at the Austrian Institute for European and Security Studies, said: “With the removal of US troops in northern Syria, which both Ankara and Tehran opposed for different reasons, Turkey and Iran’s conflicting strategic interests are now naturally coming to the forefront.”
Moreover, according to Tanchum, Iran has already fought elements of the paramilitary forces now that are now partnering with Turkey.
“Tehran is distressed that such elements are being empowered. While Iran needs Turkish cooperation in the face crippling US sanctions, Iran needs Russia’s cooperation much more,” he told Arab News.

However, Tanchum thinks that the idea Tehran would triangulate between Ankara and Moscow as a way of preserving its own position in Syria seems quite unlikely.
“If Iran has to choose between Turkey and Russia in Syria, it will choose Russia. In this sense, the previous dynamics of the Astana process are no longer in place,” he said.
However, Dr. Bilgehan Alagoz, lecturer at Istanbul Marmara University’s Institute for Middle East Studies, said that rumors about the death of the Iranian-Turkish alliance in Syria may be a bit exaggerated, at least for now.
For Alagoz, Iran is hesitant about cooperation between Turkey and the US, which has the possibility of creating a confrontation against Iran’s interests in Syria.
“On the other hand, Iran is uncomfortable with the US military presence in Syria. Therefore, Iran is facing a dilemma,” she told Arab News.
According to Alagoz, at this point Iran needs to pursue diplomacy with both Turkey and Russia.
“Thus, I do not think that the Iranian statements against Turkey will continue for a long time,” she added.
With the civil war now in its eighth year in Syria, Assad’s forces have gradually gained control of strategic cities in northwestern Idlib province, like Khan Sheikhoun, with Russian and Iranian support. The Syrian regime also attacked Turkish military observation posts in the region over the summer.
In the meantime, in a surprise decision on Monday evening, Turkey appointed former Halkbank executive Hakan Atilla, who was sentenced to prison in the US over Iranian sanctions breaches, as the new CEO of the Istanbul Stock Exchange.
