I don't know much about the Islamic Gulen movement. The article mentions a university network that is approved for their students' use. As about 0.5% of Florida Tech's students are Turkish, I am guessing that my university is on the "approved" list. Overall, Florida Tech has a very high percentage of international students and Muslims in particular. They pay the full tuition (usually without scholarships but sometimes sponsored by their governments), and I give them value for value. In 16 years I have yet to see any cases of Muslim conspiracy. The Muslim students I have met want to better themselves just like you and me.
"..changed Turkey's fundamental identity"
but I did not realize how it was done, thanks.
