Turkey has been powerful when it had the "Islamic World" under its stewardship. Being EU member would have improved the hand of "Secularists" for few years or so. Given the unraveling of EU experiment it would have at best delayed certain things, sooner or later in a generation the Turkey will look more like the Ottoman era both in its power and projection than it was for much of 20th century.
Is no one else getting really fed up with this discriminatory dimming feature on HN? It's basically "Many of us don't like what you're saying (OK) and will therefore make it difficult for those with poor sight to read it (not OK)". What is it but weak censorship? What about an alternative?
So broadly speaking, NO.
