The EU's rejection of Turkey as a member (which was not an outright rejection, but a bureaucratic stagnation to death) has pushed Turkey towards the Arab world, away from the West. The latest evidence is in its decision to lead the Arab Free Trade Zone.
The implications are potentially large. Turkey has the potential to lead the Middle East and, as I spoke of before, unite it.
Turkish ascension to the EU probably made geopolitical sense, from a strictly national power perspective. It's not clear whether anti-Turkish racism in central Europe was the primary driver to keep Turkey out, or whether it was simply a European implosion over issues like the financial crisis.
But either way, the shift in rhetoric and action by Turkey likely suggests a long-term drift away from the West, and towards the Middle East.
