From Zero Hedge:

In accordance with an energy cooperation framework agreement signed in late January, Russia will have exclusive rights to produce oil and gas in Syria.

The agreement goes significantly beyond that, stipulating the modalities of the rehabilitation of damaged rigs and infrastructure, energy advisory support, and training a new generation of Syrian oilmen. Still, the main international aspect and the key piece of this move is the final and unconditional consolidation of Russian interests in the Middle East.

From Haaretz:

“We state that from now on we refuse to cooperate in any form with the U.S. in its status of a mediator, as we stand against its actions,” Abbas told Putin at the start of talks in Moscow.

From Zero Hedge:

Two weeks after a US B-52 strike killed scores of Russian mercenaries in Syria, which according to Bloomberg and Reuters were are as many as 200, while Russia said no more than 5 Russians were killed in the attack then promptly refused to discuss the embarrassing topic further, Moscow has clearly not forgotten this latest – and most serious – escalation in the 7-year-old proxy war, and on Monday Russian Foreign Minister Sergei Lavrov warned the Trump administration not to “play with fire” as he lashed out at the U.S. over what he described as its “provocative” support for autonomy-seeking Kurds in Syria, while urging US troops in the area of Al-Tanf to “leave immediately.”

From Zero Hedge:

Confirming that the “enemy of my enemy is my friend”, YPG Kurdish fighters in north-western Syria – who as a reminder are backed by the US, the country which for 7 years has waged a proxy war to overthrow president Bashar al Assad – have struck a deal with the Russia-backed Assad regime for Syrian forces to enter the Afrin region and repel a Turkish offensive which began last month.

From The Saker:

[S]ince the US Americans have declared that they will (illegally) stay in Syria until the situation “stabilizes” they now must do everything their power to destabilize Syria…

[N]o matter what the Turks do, the US would (almost) never consider actually openly using force against them simply because the consequence of, say, a USAF strike on a Turkish army column would be too serious to contemplate…

[I]t would most likely be followed by a Turkish demand that the US/NATO completely withdraw from Turkey’s territory and airspace…

[I]f there is one actor which can seriously disrupt the US operations in northern Syria, or even force the US to withdraw, it is Turkey…

Russian efforts to drive a wedge between the US and Turkey are being greatly assisted by the US support for Israel, Kurds, and Gulenists…

[T]he best solution here would be to deliver as many Pantsir-S1 mobile Gun/SAM systems and 9K333 Verba MANPADs as possible to the Syrians and the Iranians.

From the comments:

Erdogan cannot forget that the US instigated that coup d’etat against him, and that Russia saved his life, literally, warning him of the approaching coup and sending combat planes to prevent his own plane being shot down.  Even Russian AA missile systems in Syria protected Erdogans life, the plotters receiving warnings from Russian ground crews. Erdogan knows the EU will never accept him, and Turkeys membership of NATO is more than a liability, becoming dangerous. The last thing Erdogan wants is for Turkey to be involved in a possible US war against Iran, let alone in a war against Russia, for which Turkey would pay a price…

RF will stay passive till end of World Cup (where US did not “qualify”)…

Syrian sources confirm a decision to rain down a couple of dozen Surface to Surface missiles over Israeli towns in the Golan Heights or anywhere in Israel if IAF violates Syrian air space sovereignty…

Russians are quiet due to the upcoming elections…

The US wants to spite Russia and Syria by establishing Kurdistan. But such a state would be landlocked between very hostile neighbors. It has absolutely no viability. At the same time it will destroy the US geopolitical position in the middle east. Kurdistan is poisoned fruit and if the US wants it, why should Russia stand in its way?
