Iranians tried to create sectarian conflicts in Pakistan, but failed due to the strong action of the state and the love, unity Sunnis and Shias in Pakistan have with each other. All they could do was steal away some few pilgrims from Karbala, Najaf, and Qom for proxies in Syria.
Shia Azerbaijan was abandoned by them in favor of Christian Armenia to use against Turkey, but even so they only created a bigger mess in their own country with their large Azeri minority.
Here you have Turkey, where Muslims, Sunnis, Shias, Christians, and Alevis live in peace. Can anyone point any time in Turkey's modern history when there were religious tensions?
Turkey is the model for an Islamic state based on unity between East and West, representing the strength of both, and a society which has moved beyond sectarianism. Now with Erdogan, Turkey has fully embraced its Muslim history as well. Anyone who studies modern Turkish identity has no choice but to admit its strength.
So strong was/is that identity that Europeans from UK, France, Germany, Balkans were/are ditching their culture, religion, civilization to get aboard the Turkish project. In fact the British called this phenomena among their intelligentsia, "Turning Turk."
Pakistan, Arabs, and other nations should be moving forward in this direction to create a strong, unified state which is comfortable with both modernity, Sufism, and its Muslim history.
