Kerry Strikes Possible Deal With Russia on Syria During Moscow Visit

Possible deal may include US military cooperation against terror groups in Syria

Neither side would share details, but Kerry’s announcement appeared to suggest that Russia and the U.S. reached a preliminary deal to coordinate airstrikes together against jihadist groups in Syria, potentially representing a major shift in U.S. policy in the conflict.

At Thursday's news conference, Kerry would not confirm whether the steps agreed with Moscow were the same as those laid out in the leaked proposal, though he strongly implied that they dealt with the same issues targeted in the proposal.

The proposal published in full on the Post’s website calls for the U.S. and Russia to collaborate militarily together against Jabhat al-Nusra, Al-Qaeda’s affiliate in Syria -- something long desired by Moscow. In return, the proposal would require that the Syrian air force be largely grounded.

At the news conference, Kerry first described the two main causes of the breakdown of Syria’s ceasefire as indiscriminate bombing by the Syrian government and offensives by al-Nusra. Kerry then said that he and Lavrov had “agreed to steps that if implemented in good faith can address the serious problems that I just described about the cessation.”

Kerry said that Russia and the U.S. would not be making thee steps public, saying that is “because we want them to work.” He added that the steps would have to be further developed in the coming days.

Kerry's statements suggested that the proposal leaked to the Post had been accepted in some format at least in principle by the Russians. In the leaked document, Russia and the U.S. would create a “Joint Implementation Group” based in Amman, Jordan, that would coordinate attacks on al-Nusra by Russian and U.S. military forces. Assad’s air force meanwhile would be forbidden from flying sorties in areas where al-Nusra is concentrated or in opposition-controlled areas where al-Nusra is operating.

If carried out, the proposal would represent major shifts for both Russia and the U.S. .

The U.S has regularly accused Russia and the Assad regime of using claims that it is targeting al-Nusra and the Islamic State as cover for actually hitting moderate opposition groups. The deal, if implemented, appeared to seek to end this possibility.

The removal of the Syrian air force from much of the battlefield would be a major breakthrough; continued bombing of groups involved in the ceasefire, as well as of civilians, has previously led opposition groups to suspend their participation in U.N.-backed peace talks. At the same time, U.S. officials have said al-Nusra was undermining the ceasefire by attacking the regime, often dragging more moderate groups into offensives and thereby breaching the ceasefire of which it was not a part and creating what Kerry called a "cycle of excuses" for more violence.

The potential deal was therefore meant to target these two problems.

On Thursday, Kerry made it clear that in theoir talks the two sides had not been able to yet persuade one another the deal could or would definitely be implemented, but he suggested the groundwork was sufficient to try.

Kerry said he wanted to emphasize that the deal was “not based on trust” and that there were specific steps that would have to be shown to have been carried out. But he said that the deal if carried out in good faith “has the opportunity to change the playing field significantly.”

“Let the proof be in the pudding, not our words,” he said.

The ambitiousness of the proposal and the risks around it reflect a sense among U.S. officials that time is running out to establish a lasting peace in Syria. The ceasefire brokered by Moscow and Washington in February has collapsed in many areas, while U.N.-backed talks have stalled amid the violence. Officials said that unless the two key problems undermining the ceasefire -- al-Nusra and bombing by the Syrian regime -- could be resolved jointly with Moscow, the ceasefire could collapse definitively.

“Either we find a way to do something about it or not, and if we don’t, the entire thing breaks down,” a senior State Department official said before the talks began. “And so the conversation here is about, can we find a way to address these two problems? If not, obviously that will be the end of the cessation of hostilities.”
