The question is, will America turn against Turkey, too, or are the threats to exclude them out of NATO just empty ones? It will also be interesting to see if the EU will condemn this "democratic regime" they were so quick to defend after the coup.
Mostly empty, USA (and the EU) needs Turkey for various reasons. Turkey could unleash floods of refugees into the EU if pissed off and USA needs its bases in Turkey. That's effective power. Erdogan can basically do whatever he wants right now.
