My major at university concerned the history of the Islamic World which gave me some basic ideas about various aspects of Islam. Additionally, my family comes from the Middle East, providing additional insight.
Answer 1 there are some wahhabi groups in Iraq. shia and sunni have disagreements but not conflict. shia and sunni have mainly conflict on Imamat (leadership). shia say… Imamat is one of 5 pillars of Islam and only God can select leader for people. but sunni say Imamat is not part of Islam and leader can be selected by people by any method like shura (for example for Abubakr) or by will of previous leader for example for Omar) or by people (for example for Ali). the conflict of shia and sunni has been always amplified by world Imperialism to prevent Islam from spreading in world. Answer 2 Most of the conflicts in Iraq today have little to do with theological issues. That is to say that Shiites are not killing Sunnis over whether Abu Bakr or Ali was the proper first Caliph. Do these groups have theological disagreements, yes, but that is not the cause of the friction. The conflict in Iraq also has little to do with economic factors. Unlike the Arab Spring, which arose due to dictatorial governments' failures to give out jobs, it was quite clear that the newly-created Iraqi government had no jobs to give and therefore conflict or revolution would not solve the problem. The conflict in Iraq is a conflict between ideologies. Many Westerners try to oversimplify the various "sides" of the conflict by saying "Sunnis, Shias, and Kurds" but this fails to explain why most Shia deaths in Iraq are caused by Shia (if not by Coalition Forces). Different groups want an Iraq that has a more religious base, others want a secular base. Some want a federal system, whereas others want a tribal system. Some want right-wing economics, others want socialism. Some want ethnic regional power, while others want a strong central government. Some want only a national army, while others want some ethnic militias, and while others want a fully local defense core. This makes the negotiations fraught with complexity and some groups would prefer not leave the success of their ideology to chance. (MORE)
