Well it is a start, as a snow ball it can include Iran and Iraq as well in the future. The divide between Muslim world Today is happening in Syria, Libya, Yemen, and Afghanistan.
I rather see there is a divide between a dictatorial regime vs democratic government in Muslim world after Arab spring comes. Iran and Iraq as shiah and democratic countries should stand behind other democratic Muslim countries so their blind support on Bashar regime should be stopped. It is not a Sunni vs Shiah anymore. And as more Muslim countries are likely become democratic like recent Algeria and Sudan case, it means democratic Muslim countries are getting upper hand.
Renaissance in Muslim world I would interpret as democratization of Muslim world. This idea should be protected and pushed by all Muslim democracy nations so that we can solve conflict in Syria, Libya, Yemen, and Afghanistan by enforcing democracy system to solve dispute among their people. The reason of why there is conflict there is because their people tend to solve their conflict and differences by force instead of using ballot.
But we should spare Saudi, UAE, Qatar, Oman, and Bahrain as their society are still content with Monarchy.
