Think about this:
What motive would Assad all of a sudden have to bomb civilians with chemical weapons?
I think not... Remember the USS Maine, the lies that led us into the Korean War, the Gulf of Tonkin and "weapons of mass destruction?"
U.S. imperialism uses incidents it creates while blaming others as the excuse and pretext to justify going to war.
The CIA uses murder and mayhem to undermine governments all over the world not to Wall Street's liking so I don't think it is out of character for the CIA to be behind this release of chemical weapons in Syria.
After all, it was the noted journalist Seymour Hersh who made the charge that it was Hillary Clinton who helped arrange for these so-called "Syrian rebels" to attain Sarin nerve gas.
And then we have Trump looking for a way to try to make himself appear to be a legitimate President... something that isn't possible.
