Shia–Sunni relations
Shia–Sunni discord in Iraq starts with disagreement over the relative population of the two groups. According to most sources, including the CIA's "World Factbook", the majority of Iraqis are Shia Arab Muslims (60%-70%), and Sunni Arab Muslims represent between 32% and 37% of the population. However, Sunni are split ethnically among Arabs, Kurds and Turkmen. Many Sunnis hotly dispute their minority status, including ex-Iraqi Ambassador Faruq Ziada, and many believe Shia majority is "a myth spread by America". One Sunni belief shared by Jordan's King Abdullah as well as his then Defense Minister Shaalan is that Shia numbers in Iraq were inflated by Iranian Shias crossing the border. Shia scholar Vali Nasr believes the election turnout in summer and December 2005 confirmed a strong Shia majority in Iraq.
Culture of Iran
Today of the 98% of Muslims living in Iran, around 89% are Shi'a and only around 9% are Sunni.This is quite the opposite trend of the percentage distribution of Shi'a to Sunni Islam followers in the rest of the Muslim population from state to state (primarily in the Middle East) and throughout the rest of the world. This data is from the government of Iran and most likely contains false information. It is very likely that the percentage of Muslims living in Iran is highly exaggerated as Islam is forced under the Islamic Republic's sharia law.
