Q must be right on Russia Syria

April 25, 2018: Russia is hustling to carry out some damage control in Syria after two embarrassing defeats. First, there was the loss of several hundred Russian military contractors during a failed February attack on American and Kurdish forces in eastern Syria. In April there was the U.S., British and French attack on Assad chemical weapons facilities with 105 smart bombs and missiles. The Syrian air defense system, using recently updated equipment, failed to stop any of the incoming missiles, all of which apparently hit their targets and did so nearly simultaneously. Russia later admitted it did not use its S-400 air defense system in Syria because the incoming missiles, as per previous agreements, avoided all Russian facilities. Russia still insists that the Syrian air defense system shot down a lot of the incoming missiles but has not provided any proof. Such proof would be easy to locate and display if it existed, but it doesn’t and Russia is left insisting that its S-400 system, which it recently sold to Turkey, could have shot down the incoming missiles. Meanwhile, Russia says it is sending some S-300 batteries to Syria to upgrade the Syrian air defenses and that these would also knock down incoming missiles. It is uncertain when the S-300 systems will arrive in Syria, or whether they will be sent at all.
The fact remains that Russia had a chance to demonstrate the effectiveness of the S-400 and refused to engage. Finally, there was the event that triggered the American led missile attack and that was the frequent recent use of nerve gas by the Assad government. Russia denies this is happening but the UN investigators are convinced and this puts a bad light on the Russian effort in 2013 to avoid Western air attacks on Assad by guaranteeing that the Assads would dismantle their chemical weapons facilities and account for all their chemical weapons so they could be destroyed. The continued use of nerve gas and other chemical weapons by the Assads shows the 2013 Russian guarantee to be worthless. Russia says it is all part of a NATO plot to discredit Russia. Despite the confrontational situation leading up to the missile attack and its aftermath (Russia insisting the gas attack was staged by Britain) the Russians and Americans kept their liaison channels open and active. Some with Russia and Israel.
