:hihi: No it doesn't. Just a few decades ago there was very serious talk of pan-Arabism. Egypt and Syria actually even went so far as to join together for a time and after a fashion (the UAR). Saddam Huessin and his Baath party is a product of that philosophy.
The idea that they're hopelessly divided along religious lines is absurd and an unfortunate product of extremist elements like wahhabism.
