Pence announces Syria ceasefire that appears to give Turkey everything it wants

The deal appears to secure Turkey most of its military objectives, forcing America's one-time allies in the fight against ISIS -- Kurdish forces -- to cede a vast swath of territory, with one senior US official very familiar with operations in Syria telling CNN that the deal meant the US was "validating what Turkey did and allowing them to annex a portion of Syria and displace the Kurdish population."

The Turkish government is insisting that the agreement is not a ceasefire, but only a "pause" on operations in the region, reflecting Ankara's views of the status of the Syrian Kurds.

As part of the deal, Pence said Turkey "will pause Operation Peace Spring in order to allow for the withdrawal of (Kurdish) YPG forces from the safe zone for 120 hours," referring to Ankara's official name for the unilateral military offensive.

"All military operations will be paused, and Operation Peace Spring will be halted entirely on completion of the withdrawal," Pence said.

"This also includes an agreement by Turkey to engage in no military action against the community of Kobani," he continued, referring to the Kurdish-held city on the border of Syria.

Pence said the Turkish operation would end when the YPG forces complete their withdrawal.

Pence said during a press conference announcing the agreement that the US is "going to be using all the leverage that we have of having fought alongside Syrian Democratic Forces in the battle against ISIS to facilitate their safe withdrawal," adding that the negotiated "outcome will greatly serve the interests of the Kurdish population in Syria."

Once a permanent ceasefire is achieved, Pence said the President would withdraw the sanctions that were placed on Turkey in the last week.

However, Turkish Foreign Minister Mevlut Cavusoglu said during a televised press conference Thursday that the agreement "is not a ceasefire."

"We will pause the operation for 120 hours in order for the terrorists to leave," Cavusoglu said, referring to the Kurds. "We will only stop the operation if our conditions are met."

Trump says agreement is 'an amazing outcome'

Trump called the agreement "an amazing outcome" and said he was hopeful that the ceasefire would last more than five days.

"The Kurds are very happy. Turkey is very happy. The United States is very happy. And you know what? Civilization is very happy. It's a great thing for civilization," Trump remarked after Pence's press conference.

There has been no public statement from Kurdish YPG forces that they have agreed to withdraw, although Pence said he had spoken with YPG leadership.

But as late as last week, Gen. Mazloum Kobani Abdi, the commander of the Kurdish-led Syrian Democratic Forces told a senior US diplomat, "You are leaving us to be slaughtered," demanding to know whether the US is going to do anything to protect Syrian Kurds as Turkey continues its military operation targeting America's Kurdish allies in Syria. He also pressed the US about not ceding territory to Turkey.

According to an internal US government readout obtained exclusively by CNN, the general asked for clarification on the US position regarding Turkey's demand for a 30-kilometer zone under its control: "Are you asking me to surrender 30km of my land and then discuss these points? Let me make sure I understand, the United States of America wants Turkey to occupy this land?"

A senior US official tells CNN that the deal made with Turkey is essentially validating the Turkish offensive.

"This is essentially the US validating what Turkey did and allowing them to annex a portion of Syria and displace the Kurdish population," the official said. "This is what Turkey wanted and what POTUS green lighted. I do think one reason Turkey agreed to it is because of the Kurds have put up more of resistance and they could not advance south any further as a result. If we don't impose sanctions then Turkey wins big time."

Brett McGurk, the former special presidential envoy for the Global Coalition to Defeat ISIS, tweeted that new agreement could not be implemented.

"The US just ratified Turkey's plan to effectively extend its border 30km into Syria with no ability to meaningfully influence facts on the ground. Turkey says it's the entire border from the Euphrates to Iraq (450x30km) to be controlled by its military forces. Non-implementable," McGurk wrote.

Ceasefire similar to previous agreement

Thursday's proposed ceasefire seems very similar to the previous "Security Mechanism" agreement reached with Turkey earlier this year.

As part of that agreement, the US convinced the Syrian Democratic Forces to dismantle their defensive fortifications and pull fighters from the border to appease Turkey.

The US also conducted joint patrols and shared intelligence with the Turkish military as part of that arrangement.

The Kurds complied with the request to pull back and dismantle their fortifications and the US said the agreement was working ahead of schedule. Turkey opted to invade despite those efforts.

Now that the US has pulled out of all locations in northern Syria apart from Kobani, it will be nearly impossible for the US to monitor, much less enforce, a ceasefire.

Asked about the prospects of a ceasefire given the fate of the now defunct security mechanism agreement, a senior US administration official said recently, "We are very aware that the Turks entered into an agreement with us and they then decided that they would pull out of that agreement and we're very concerned about that happening again."
