Are we developing better ties with Russia on the sly?

De-confliction of air ops w/Russia continue. Today they conducted ops in vicinity of #Raqqah. So did @CJTF-OIR.

After seeing the above tweet about "deconflicting" the battlespace with Russia, I'm left wondering if we're not developing better ties with Russia on the sly.  During the Obama Admin we saw US and Russian fighters almost getting into furballs over Syria, now they seem to almost be on the verge of conducting joint operations.

What I find puzzling is that just yesterday Mattis talked about us NOT being able to work with Russia and then spokesman in the region releases this tweet?

Extremely curious.
