As I remember, Greece after 400 years of Muslim/ Ottoman oppression - which brought the whole region to penury - with the help of Britain and others, including moral support from the likes of Lord Byron, finally rid themselves of Islam in the 1830's, and the poor *** are now being re-invaded along with the rest of Europe on a daily basis.
Every country, throughout every period in history that has been overrun by Islam has fallen into ruin and dilapidation. I see it, perhaps you see it, but why the hell don't they see it?
