Religion
It's all about religion. That's where te real power of mass manipulation is situated. So I really believe that Iran is able to destabilise Iraq. A new Persia may be in the making.
They have nothing to do with the Arabs it's a different kind of bread.
Turkey will NOT get in the EU and will get closer to Iran and Iraq.
But what really is going on is that the Arabs do not really care about what is going on in Israel with regard to the faith of the Palestinians. The Persians have a different agenda in this regard.
