Things are about to take a hard turn away from the US with Turkey. Perhaps this is the start of Turkey not just saying rhetoric, but actions. They themselves seem tired of playing coy to the whole Greater 
project themselves.
In Friedman’s Next 100 Years, it is set for Turkey and Japan to ally against America. Turkey will become a major regional power in the ME and will have a diminished status.

In the 2020s and 2030s, three main powers will emerge in Eurasia: Turkey, Poland, and Japan. Initially supported by the United States, Turkey will expand its sphere of influence and become a regional power, much as it was during the time of the Ottoman Empire. The Turkish sphere of influence will extend into the Arab world, which will have increasingly fragmented by then, and north into Russia and other former Soviet countries. Israel will continue to be a powerful nation and will be the only country in the immediate region to remain outside the Turkish sphere of influence. However, Israel will be forced to come to an accommodation with Turkey due to Turkey’s military and political power.
Even if turkey just started covertly supplying weapons, it would be a significant turning point. Turkey is one of the 4 major manufacturers and exporters of advanced military hardware. Like the US, China, and Russia— Turkey is one of the sources of so-called 5th generation military hardware.
Currently the most advanced weapons available to the resistance axis come from Iran. Iranian weapons are admirable, especially when one factors in the decades of sanctions, but Turkish military hardware is comparable to top end US, Chinese, and Russian military hardware. Would be high attrition military hardware like single use drones, manpads, and cruise missiles.
