Turkey has the 2nd largest military in NATO and that's why their sliding into the orbit of the SCO countries is so important. The Saudis will not be allowed to kill their peg. Qatar, on the other hand, will and very soon.

They will fight this for a little while but once they see that the resolve is similar to that which went after the Ruble in 2014, they'll stop defending it and start accepting Euros/Yuan/etc. for their gas.

Why do you think they pledged to invest in American Airlines and buy some jets, to smooth over the hard feelings with Trump over their next logical course of action.
