The Brussels-based think tank criticizes the U.S. insistence on supporting Prime Minister Nuri al-Maliki's coalition government. It calls instead for the international community to open talks with all Iraq's warring parties.
The document came a day after the U.S. Defense Department issued a report saying the number of Iraqi insurgent attacks on U.S. troops and Iraqi security forces and civilians has risen to a new record high.
Statistics released by the Pentagon say the average number of insurgent attacks per week rose to 959 during the three months to November 10.
