Can Russia Revive the Adana Agreement between Syria and Turkey?

Whenever Turkey threatens to launch a military operation in northern Syria to establish a “safe zone,” Russia puts on the mediation table the revival of the Sochi Agreement on the east of the Euphrates, in preparation for the implementation of the Adana Agreement. The latter was signed by Ankara and Damascus in July 1998, establishing security cooperation between the two parties and allowing the Turkish army to pursue the Kurdistan Workers Party (PKK) deep into Syrian territory.

Since the Russian war in Ukraine, Turkish President Recep Tayyip Erdogan has activated his old plan to establish a safe zone with a depth of 35 kilometers, trying to benefit from the improvement of Ankara’s negotiating position due to Washington and Moscow’s “need” for Turkey’s role.

America clearly announced its rejection of the military operation east of the Euphrates, while Moscow mediated between Damascus, Ankara and the Kurds, and deployed Syrian army forces in various areas in the north of the country to “deter” the Turkish army, ahead of the Russian-Turkish-Iranian summit in Tehran on Tuesday.

Ankara wants new incursions linking its military “enclaves” in northern Syria, namely the Euphrates Shield, north of Aleppo, which was established in 2016, the Olive Branch in Afrin in 2018, the Peace Spring, eEast of the Euphrates, formed at the end of 2019, and the Peace Shield, at the start of 2020.

Moscow proposes either activating the Adana Agreement or the full implementation of the Sochi Agreement of 2019, in addition to a military memorandum between Damascus and Qamishli in exchange for an agreement between Ankara and Washington. Below is a review of the most important agreements:

What are the terms of the Adana Agreement?

After Turkey threatened to attack Syria in mid-1998, late Egyptian President Hosni Mubarak mediated between the two parties, until a security agreement was concluded between Ankara and Damascus in the Turkish city of Adana. The text of the agreement and its annexes included, among others, the following items:

- As of now, the leader of the Kurdistan Workers’ Party, Abdullah Ocalan (detained in Turkey since the beginning of 1999), will not be in Syria, and will certainly not be allowed to enter Syria.
- PKK members abroad will not be allowed to enter Syria.
- As of now, PKK camps will not operate on Syrian soil, and will certainly not be allowed to become active.
- Many members of the PKK were arrested and referred to the court. The lists containing their names were prepared and submitted by Syria to the Turkish side.
- Syria, based on the principle of reciprocity, will not allow any activity launched from its territory that harms the security and stability of Turkey. Nor will Syria allow the supply of weapons, logistical materials, and financial and promotional support for PKK activities on its soil.
- Syria has classified the PKK as a terrorist organization, and has banned the activities of the party and its affiliated organizations on its territory, along with other terrorist organizations.
- Syria will not allow the PKK to establish camps or other facilities for training and shelter purposes or to conduct commercial activities on its soil.
- Syria will not allow members of the Kurdistan Workers Party to use its territory to cross to third countries.
- A direct telephone line is immediately operated between the higher security authorities of the two countries.
- The two parties appoint special security representatives in their diplomatic missions in Ankara and Damascus. Those are presented to the authorities of the host country by the heads of the mission.
- Annex No.3: As of now, the two parties consider that the border disputes between them have ended, and that neither of them has any claims or rights due in the territory of the other party.
- Annex No. 4: The Syrian side understands that its failure to adopt the security measures and duties stipulated in this agreement gives Turkey the right to implement all necessary security measures inside Syrian territory to a depth of five kilometers.

What does the Adana Agreement mean at the political and security levels?

• It gives the Turkish army the right to pursue the PKK at a depth of five km in northern Syria, according to Annex No. 4.
• Damascus relinquishes any claim to its rights in Iskenderun (Hatay Province), which Turkey annexed in 1939, according to Annex No. 3.
• The PKK, led by Abdullah Ocalan, is considered a “terrorist organization”, in accordance with the provisions of the agreement.
• Ankara interprets the agreement as meaning that the Kurdish People’s Protection Units (YPG) is a “terrorist organization”, as an extension of the PKK.
• The agreement means the start of direct security contacts, knowing that the Director of Syrian National Security, Ali Mamlouk, has held several meetings with Turkish Intelligence chief Hakan Fidan.
• It also means re-operating the Turkish embassy in Damascus and the Syrian embassy in Ankara, noting that Damascus has a consulate in Istanbul, given that the agreement requires the appointment of a security liaison officer in each embassy.
• The agreement entails “indirect contacts” acknowledged by Turkish Foreign Minister Mevlut Cavusoglu, and Ankara’s recognition of the legitimacy of the Syrian government, as its required many procedures, including the formation of a joint committee and the operation of a hotline.
• The agreement offers an alternative to the Turkish-American understanding on the depth of the “buffer zone” of 32 kilometers in northeastern Syria, and opens the way for the implementation of the Sochi Agreement between Erdogan and President Vladimir Putin in October 2019, following former US President Donald Trump’s decision to withdraw his forces from the east of the Euphrates, which paved the way for a Turkish attack at the time.

What is the 2019 Sochi Agreement?

Erdogan and Putin have agreed on 10 points, including:

The determination to combat terrorism in all its forms and manifestations, and to disrupt separatist projects in Syrian territory.
• In this context, the status quo will be preserved in the current Operation Peace Spring area, which covers Tel Abyad and Ras al-Ain, at a depth of 32 kilometers.
• Both parties reaffirmed the importance of the Adana Agreement. Russia, for its part, will facilitate the implementation of this agreement under the current circumstances.
• The Russian military police and Syrian border guards will enter the Syrian side of the Syrian-Turkish border, outside the area of Operation Peace Spring, in order to facilitate the removal of the Kurdish People’s Protection Units and their weapons.
• Turkey and Russia will conduct joint patrols west and east of the Operation Peace Spring area, at a depth of 10 km, with the exception of the city of Qamishli.
• All members of the Kurdish People’s Protection Units and their weapons will be removed from Manbij and Tal Rifaat.

What about the US-Turkish agreement of 2019?

Prior to that, an agreement was signed between Erdogan and former US Vice President Mike Pence in October 2019, which consisted 13 items. Those included, among others:
• The United States and Turkey confirm their relationship as NATO partners, and the United States understands Turkey’s legitimate security concerns on its southern border.
• The two sides agreed on the need to maintain the safety of the area, in order to address Turkey’s national security concerns and seize heavy weapons from the Kurdish People’s Protection Units.
• The Turkish side temporarily stops Operation Peace Spring to allow the withdrawal of the People’s Protection Units from the Spring area. Operation Peace Spring will be halted upon completion of this withdrawal.
• Once Operation Peace Spring is stopped, the United States agrees not to continue imposing sanctions pursuant to the October 14, 2019 Executive Order banning property and suspending entry to certain persons contributing to the situation in Syria.

How did the Syrian army return to the east of the Euphrates?

In parallel with these Russian-Turkish-American agreements that followed Trump’s withdrawal from Turkey’s borders in northeastern Syria - which opened the way for Ankara’s incursion – a memorandum of understanding was reached between the Syrian Democratic Forces, the allies of Washington, and Damascus. Here are some of its points:

• The Syrian Democratic Forces (SDF), which includes the Kurdish People’s Protection Units, agreed to enter the Syrian Arab Army and extend its control over the entire region, starting from Ain Diwar in the east, and up to Jarablus in the west, where the forces will be deployed from three axes:
1. Tabqa axis in the north towards Ain Issa and its countryside, and in the north, towards the Syrian-Turkish border at Tal Abyad and towards the west.
2. The Manbij axis towards Ain al-Arab on the Syrian-Turkish border, to the point of Tal Abyad and towards the west.
3. Al-Hasakah-Tal Tamer axis to Ras al-Ain and from it to the east to Qamishli and then to al-Malikiyah and towards the south.
4. The forces are deployed in the Manbij area, starting from Arima and along the Sajour River line, according to the previous agreement on the deployment of forces in Arima.

In this memorandum, “the (SDF) forces affirmed their readiness to preserve the unity and territorial integrity of the Syrian Arab Republic and under the flag of the Syrian Arab Republic, and to stand by the Syrian Arab Army in the face of Turkish threats to the Syrian territories, led by President Bashar al-Assad.”

However, Trump’s keeping his forces east of the Euphrates has led to the slow implementation of this memorandum. In the face of recent Turkish threats, Russia returned to push the SDF and Damascus to implement the 2019 memorandum.

Just as Russia implemented the “disengagement” agreement between Syria and Israel and deployed international forces in the Golan, it seeks to put the interim agreements into effect, leading to the reactivation of the Adana Agreement, which would pave the way for “legitimizing” the government and expanding its sovereignty in the country.

Russia had previously suggested this option during the preparations for the tripartite summit in Tehran, and will continue to push for its implementation.

A Week Into the Fragile Israel-Iran Peace Agreement, Here's What We Still Don't Know

It's been a week since the United States pressed Israel and Iran into a truce, ending a bloody, 12-day conflict that had set the Middle East and globe on edge.

The fragile peace, brokered by the US the day after it dropped 30,000-pound "bunker-busting" bombs on three of Iran's key nuclear sites, is holding. But much remains unsettled, The Associated Press reported.

How badly Iran’s nuclear program was set back remains murky. The prospects of renewed US-Iran peace talks are up in the air. And whether US President Donald Trump can leverage the moment to get Israeli Prime Minister Benjamin Netanyahu 's government and Hamas focused on a ceasefire and hostage deal that brings about an end to the 20-month war in Gaza remains an open question.

Here is a look at what we still don't know:

How far Iran's nuclear program has been set back Trump says three targets hit by American strikes were “obliterated.” His defense secretary said they were “destroyed.”

A preliminary report issued by the US Defense Intelligence Agency, meanwhile, said the strikes did significant damage to the Fordo, Natanz and Isfahan sites, but did not totally destroy the facilities.

Rafael Grossi, head of the International Atomic Energy Agency, said on CBS’ “Face the Nation” on Sunday that the three Iranian sites with “capabilities in terms of treatment, conversion and enrichment of uranium have been destroyed to an important degree.” But, he added, “some is still standing” and that because capabilities remain, “if they so wish, they will be able to start doing this again.” He said assessing the full damage comes down to Iran allowing inspectors access.

What future US-Iran relations might look like

After the ceasefire deal came together, Trump spoke of potentially easing decades of biting sanctions on Tehran and predicted that Iran could become a “great trading nation” if it pulled back once-and-for-all from its nuclear program.

The talk of harmony didn't last long.

Ali Khamenei, in his first public appearance after the ceasefire was announced, claimed Tehran had delivered a “slap to America’s face." Trump responded by suggesting the supreme leader own up to the fact Iran “got beat to hell. The president also said he was backing off reviewing any immediate sanction relief, because of Khamenei's heated comments.

White House officials say the US and Iran are already in early discussions about resuming negotiations that had ended after Israel began launching strikes. But Iranian Foreign Minister Abbas Araghchi says there's no agreement in place to restart talks.

It's unclear if Iran's leadership is ready to come to the table so soon after the fighting has ended — especially if Trump holds to the position that Iran must give up nuclear enrichment for even civilian use. And Trump has offered conflicting statements about his commitment to talks. “We may sign an agreement,” he said Wednesday at a NATO summit press conference. He added, “I don’t think it’s that necessary.”

What role Iran's supreme leader will play

Khamenei's age and recent diminished appearance have raised questions about the scope of his involvement in US-Iran relations and Iran's response to both American and Israeli strikes. But despite having spent the last few weeks in a bunker as threats to his life escalated, there is little indication that Khamenei does not still reign supreme over the country's massive military and governmental operations.

Khamenei has ruled three times longer than his predecessor, the late Ruhollah Khomeini, and has shaped life for the country's more than 90 million people perhaps even more dramatically.

He entrenched the system of rule by the “mullahs,” or Shiite Muslim clerics. That secured his place in the eyes of hard-liners as the unquestionable authority, below only that of God. At the same time, Khamenei built the paramilitary Revolutionary Guard into the dominant force in Iran’s military and internal politics.

How Iran might strike back Iran's retaliatory missile attacks on a US base in Qatar following the American bombardment were sloughed off by the White House as a half-hearted, face-saving measure. The US was forewarned and the salvos were easily fended off.

Yet Iran remains a persistent threat, particularly via cyberwarfare. Hackers backing Tehran have already targeted US banks, defense contractors and oil industry companies — but so far have not caused widespread disruptions to critical infrastructure or the economy.

The US Department of Homeland Security last week issued a public bulletin warning of increased Iranian cyber threats. And the US Cybersecurity and Infrastructure Security Agency, is urging organizations that operate critical infrastructure like water systems, pipelines or power plants to stay vigilant.

Whether the Israel-Iran ceasefire will hold It remains a fragile peace.

Immediately following the US strikes, Trump got on the phone with Netanyahu and told the Israeli leader not to expect further US offensive military action, according to a senior White House official who was not authorized to comment publicly about the sensitive diplomatic talks.

But even as he agreed to deal, Netanyahu made clear that Israel will strike again “if anyone in Iran tries to revive this project.”

The ceasefire deal came without any agreement from Tehran on dismantling its nuclear program. Khamenei claims the attacks “did nothing significant” to Iran's nuclear facilities.

Trump expressed confidence that Iran, at the moment, has no interest in getting its nuclear program back up. “The last thing they’re thinking about right now is enriched uranium,” Trump said.

Still, Trump says he expects Iran to open itself to international inspection to verify that it doesn’t restart its nuclear program by the International Atomic Energy Agency, the UN nuclear watchdog, or some other organization "that we respect, including ourselves.”

Whether Trump can now press Netanyahu on Gaza

The president took a big gamble with his decision to order strikes on Iran's nuclear fortress.

As a candidate, he promised to quickly end Russia's brutal war in Ukraine and the Israel-Hamas conflict in Gaza, but has failed to find a resolution to either. He also vowed to keep the US military out of foreign conflicts.

But after helping Israel with US strikes on Iran, Trump — in conversations with Netanyahu and other world leaders in recent days — has made clear he wants a deal completed soon, according to two people familiar with the private discussions and were not authorized to comment publicly.

On Friday, Trump told reporters, “We think within the next week we’re going to get a ceasefire.”

Trump didn't offer any further explanation for his optimism. But Israeli Minister for Strategic Affairs Ron Dermer is expected to be in Washington this week for talks on a Gaza ceasefire, Iran and other matters, according to an official familiar with the matter. The official spoke on condition of anonymity because they were not authorized to speak to the media.
