The government policy arm that calls itself the US news media has begun to denigrate in advance the work of the UN investigators on chemical weapons. The fear is that the UN will say that the rebels in Syria were the perps in the use of chemical weapons. The technique for negating that in the minds of the US masses is to ridicule the process in advance.
The jihadi rebels are waging war against Sunni Kurds in Northeast Syria and driving many as refugees into Iraq. You won't hear much about that in the MSM in the US either.
The Syrian Army and Alawi militias have driven the jihadi rebels from the territory they had taken in the north of the Alawi country in Syria. There won't be much on that either. pl
