So, now we have allegations that the Syrians are planning an imminent chemical attack from members of the Trump administration.

First, as was noted by Sy Hersh,  there probably wasn’t a gas attack by the SAA (Syrian Arab Army, i.e. Assad) Khan Sheikhoun, and second, the war is going pretty well for Damascus these days, so another attack makes no sense.

I would note that the statements are assigning direct culpability to Russia and Iran should an attack occur, which implies that someone is trying to instigate an attack against one or both of them.

My guess is that someone wants to hit Iran, and is trying to get the Russians to keep their head down, though there is also the possibility that this is an attempt to deflect attention from the aforementioned Hersh story:

The United States said Tuesday that it has observed Syrian chemical warfare personnel visiting known production facilities, suggesting that President Bashar al-Assad’s government is preparing fresh strikes on the rebel-held north of the country. 

The White House warned late Monday that the Assad government would pay a “heavy price” for any such strikes, indicating publicly for the first time that it believes the Assad government is capable of launching new chemical attacks.

We really need to disentangle ourselves from the the Gulf monarchs supporting Jihadists in Syria (Saudi Arabia and Qatar largely, though they support different ones), and end the support  own state security apparatus for them as well. (There is no moderate opposition outside of the Kurds)

We are being played for suckers, and it will be American blood and treasure that will be wasted as a result.
