Baghdad (CNN) -- As the last U.S. soldiers exited Iraq Sunday and debate was raging about the nation's future, political crisis erupted in Baghdad that raised fears of more sectarian strife to come. Iraqiya, a powerful political bloc that draws support largely from Sunni and more secular Iraqis, said it was boycotting parliament, a move that threatens to shatter Iraq's fragile power-sharing government. The move pits the largely Sunni and secular coalition against the government of Shiite Prime Minister Nuri al-Maliki. Iraqiya contends al-Maliki is trying to amass dictatorial power and many believe al-Maliki was simply waiting for the Americans to leave before making his move.
