Moreover, I do not know if it is true that Moscow warned the President of Turkey of the coup, and I do not know if Washington was behind the coup. Therefore, I do not know how to weigh the scales.  As I see it, whether Turkey stays with Washington or realigns with Moscow depends first of all on whether or not Moscow warned Turkey and whether or not Washington was behind the coup.  If this is what Erdogan believes, whether true or false, Erdogan is likely to align with Russia.  However, other factors will also influence Erdogan's decision.  For example, Erdogan's belief about how resolute Putin is to standing up to Washington.

Erdogan will not want to align with Russia if he thinks Russia is not up to Washington's challenge.  Erdogan sees Putin endlessly asking for Washington's cooperation, and Erdogan understands that Washington sees this as a sign of Russian weakness.  Washington slaps Putin in the face, and Putin replies by asking for cooperation against ISIS.  I understand why Putin responds this way.  He wants to avoid a war between US/NATO and Russia that neither side can win.  Putin is a man of peace and accepts affronts in order to save life. This is admirable.  But that might not be the way Erdogan sees it.  Erdogan might see it like Washington sees it: weakness.
