The Iraq war began on March 20, 2003, to rid Iraq of a dictator and eliminate his weapons of mass destruction. The images remain fresh even as the memories fade - the blinding flash of "shock and awe" bombing, the square-jawed confidence of an American president leading his people into war, the cowering prisoner trembling on the ground in the face of a small piece of American power.

Bloody attacks launched by terrorists who thrived in the post-invasion chaos are painfully still frequent, albeit less so than a few years back, and sectarian and ethnic rivalries are again tearing at the fabric of national unity.
