As of today roughly half the Turkish Admirals and a fifth of the Generals are in prison. Look up the ‘Ergenekon’ plot.
I checked the Wikipedia entry. It was difficult to make sense of it. As near as I could tell, the military and politicians, before Erdogan, were stirring up trouble against the Kurd separatists in the southeast? And now, Erdogan has used that scandal/plot to purge the military of its secular leadership - is that about right?
