This "new doctrine" has nuclear armed Chinese and Russian dictatorial hard men fingerprints all over it! And given that is so, not one that the anyone in the ME dares buck!

Alan, A lot of flapping but no flying.
The ME is looking to serve it's own interests just as the US after the British have done.
Are you disappointed to see cultures advancing without an Anglo Saxon Howdy Doody permit?
Please tell me you were not thinking that the Anglo influence was going to be predominant in world affairs forever and a day.
Thieving and conniving may be art forms but there's a limit as to how long you can get away with it.

The Saudi's have been held hostage to the US for too long, and saw a way out of that racket, to instead embrace the multi-polar world.
That's why they've joined BRICS and the SCO and have made a ceasefire in the war in Yemen, which was making the US military industrial complex lots of money. War is good business for the US.

Nations moving away from the western monetary system and doing trade in their own currencies instead of US dollars will see a continuing decline in the fortunes of the US and boost the capital markets of these nations emerging economies. Nations holding reserves of currencies other than the US will then invest in those emerging markets.

Nations left to stick with the US dollar will see a decline in the value of their US currency reserves and an increase in the cost of trade.

The regional super-power in the Middle East is Israel, not China.

These developments are a direct result of the re-ascent of Netanyahu and the resulting disintegration of Israel from within. The Saudis are afraid that once Israel is no more, they would have to face Iran and Syria on their own, thus out of weakness they must make peace with the above evil regimes.

Hopefully, once Netanyahu is finally behind bars, the Saudis will reverse these changes.
