It seems clear that DC must have turned a blind eye to Turkey's brutal hammering down of the "coup" participants in return for Erdogan's promise to invade Syria and support the US agenda.
But what is the US agenda? Consider these Bible verses:
The burden of Damascus. Behold, Damascus is taken away from being a city, and it shall be a ruinous heap.
The cities of Aroer are forsaken: they shall be for flocks, which shall lie down, and none shall make them afraid.
The fortress also shall cease from Ephraim, and the kingdom from Damascus, and the remnant of Syria: they shall be as the glory of the children of Israel, saith the Lord of hosts.
Isaiah 17:1-3 KJV
Damascus is waxed feeble, and turneth herself to flee, and fear hath seized on her: anguish and sorrows have taken her, as a woman in travail.
How is the city of praise not left, the city of my joy!
Therefore her young men shall fall in her streets, and all the men of war shall be cut off in that day, saith the Lord of hosts.
And I will kindle a fire in the wall of Damascus, and it shall consume the palaces of Benhadad.
Jeremiah 49:24-27 KJV
Ultimately, everything the US does in the Middle East (including the destruction of Syria) is for the glory of the children of Israel.
