See this article from Slate which reports the French are opposed to Turkey joining the European Union. For those of you whose geography is a little shaky, Turkey is partially a southern European nation, although mostly an Middle Eastern nation. Politically, Turkey used to be a secular nation whose citizens were mostly Islamic; today Turkey is becoming an Islamic state. It is Turkey's Islamization that is causing the French to say "no."
Turkey becoming more Islamist is bad news for everybody. It is bad news for Turkey as Islamic states almost always are retrograde. It is bad news for Europe which thereby loses influence in the Islamic world. It is bad news for NATO of which Turkey is a member, but may not be a member much longer. It is bad news for all non-Islamic nations whose ships wish to sail the Black Sea, as Turkey controls both sides of the narrow waterway giving access thereto.
On the other hand, France showing some backbone with respect to resisting the creeping Islamization of Europe is good news. We can hope to see more of the same.
