Before the Iraq war began, the Pentagon was planning for a mass exodus of refugees. When the initial invasion went so fast, that was one of the many predictions that did not come true. Now, after years of deadly violence, it has. The UN's refugee agency says there's been "abject denial" of Iraq's humanitarian crisis by the rest of the world. Tim Irwin, spokesman for the UN's High Commissioner on Refugees, says some 50,000 people are fleeing their homes every month, ending up in Jordan, Syria and other parts of Iraq.
