Outlook: Fifteen years of war have devastated the Christian community of Iraq. During the U.S. occupation of Iraq (2003-2011), 1 million Christians emigrated from Iraq. The rise of the Islamic State of Iraq and the Levant/Syria (ISIL or ISIS) exacerbated what was already a fragile existence for Iraqi Christians. In 2014 the U.S. House of Representatives passed a concurrent resolution recognizing the actions taken by ISIL against Iraqi Christians and other minorities as genocide. ISIL no longer holds any territory in Iraq, but the damage done to Christian communities may be irreparable. Over two-thirds of the pre-war Christian community have either been displaced or killed.
