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.
Xenophobia and racism in the Middle East
During 1987–1988, Iraqi forces carried out a genocide against the Iraqi Kurds that claimed the lives of hundreds of thousands of people.
The UN reports that although Christians comprise less than 5% of Iraq's population, they make up nearly 40% of the refugees fleeing Iraq. More than 50% of Iraqi Christians have already left the country since 2003. Iraq's Christian community numbered 1.4 million in the early 1980s at the start of Iran–Iraq War. But as the 2003 invasion has radicalized Islamic sensibilities, Christians' total numbers slumped to about 500,000, of whom 250,000 live in Baghdad.
