Russia has provided evidence that Washington is collaborating with ISIS in attacks on Russian forces. http://russia-insider.com/en/politics/breaking-russia-presents-satellite-proof-us-troops-collaborating-isis-syria/ri21030
In one Washington-directed attack, ISIS tried to capture 29 Russian military policemen. However, Russian special forces entered the fray, and the result was spectacular losses for ISIS. http://russia-insider.com/en/military/us-secret-services-tried-nab-29-russian-troops-syria-and-got-their-butts-kicked-russian
In another attack Washington-directed attack, Russian General Valery Asapov and two Russian colonels were killed in an attack that violated agreements. http://www.moonofalabama.org/2017/09/syria-us-centcom-declares-war-on-russia.html#more
Sooner or later it will dawn on the Russian government that Washington is not a rational government with which diplomacy can be practiced, peace pursued, and agreements reached. Sooner or later it will dawn on the Russian government that far from being rational, Washington is a criminally insane collection of psychopaths in thrall to the military/security complex which, in turn, is in thrall to its massive profits.
In other words, for the powerful interest groups that control the US government, war is a profit center. No amount of Russian diplomacy can do anything about this fact.
It is unfortunate that the Russian government did not realize what it was dealing with. If the Russian government had not projected its own rationality on Washington, the war in Syria would have been over a couple of years ago. Instead, hoping for a settlement, the Russians were stop-go/stop-go, which gave Washington time to recover from the shock of Russian intervention and put in place plans to partition Syria in order to keep the conflict alive forever. Having dallied in hopes of a settlement, the danger of which The Saker warns us is real. http://thesaker.is/very-dangerous-escalation-in-syria/
With the public in its pocket, the military/security complex will increase its reckless provocations of Russia.
