TEHRAN, Iran — In public, it was all about economies, treaties and bilateral relations. Behind closed doors, however, the visit to Iran by Turkish Prime Minister Recep Tayyip Erdogan was all about Syria, Syria and Syria.

“There are still differences, that’s obvious, but they’re not as crucial as they were before,” a source in Tehran commented to Al-Monitor in discussing Erdogan's visit. “Almost two years ago, Erdogan came to Iran and insisted on meeting [Supreme Leader Ayatollah Ali] Khamenei to tell him that Iran’s bet on Assad would not yield any benefit. Back then, the leader told the Turkish guest, review your policies, your strategies, and come back. [Bashar al-] Assad won’t fall.”

Erdogan is back, and he is still in favor of toppling Assad, but according to the source, he is almost convinced that this is only a wish.

“There are alternatives that have been discussed during the past months, and in this visit, they were finalized. Turkey has its own people in the opposition, and they’ve been isolated by the current backed by Saudi Arabia,” the source explained. “The need for change in Syria can be met by bringing together both the regime and the opposition. [These] talks can be more efficient than the ones taking place in Montreux. Even if it took place at the same location, the idea is giving the talks a strong push, with both regional powers playing a positive role in convincing their allies to come to terms.”
