The Trump Administration seems to be slipping into that same destructive set of priorities in Syria. The Washington Post this week quoted an unnamed Administration official as saying that "right now, our job is to help create quagmires [for Russia and the Syrian regime] until we get what we want."

As ever, what the US really wants is to have a dominant position in post-war negotiations, so they can dictate the form that post-war Syria takes. This means ensuring that the Syrian government doesn't win the war outright.

That's not as realistic as it once was, with the Assad government, backed by Russia, having retaken virtually all of the rebel-held territory except for a far north bastion in Idlib, dominated by al-Qaeda. This means the US now has to save al-Qaeda to keep the war going, which if we're being honest has been a recurring undercurrent in US policy in Syria for years.

It is this desire that has the US repeatedly threatening Syria and warning them not to attack Idlib. It is this desire that is sparking almost daily US threats to intervene militarily if the Idlib offensive involves chemical weapons. Most importantly, it is this desire that has Russia very much believing media reports that the rebels could "stage" a fake chemical attack just to suck the US into the war, and be fairly confident it would work.
