Inside Story Americas - Have lessons been learnt from the Iraq war?

In March 2003, the United States launched an invasion of Iraq. It was a war predicated on the false claim that Saddam Hussein's weapons of mass destruction posed an imminent threat to US and British interests. American forces took Baghdad on April 9, 2003, but the US entanglement was just beginning. Hundreds of thousands of Iraqis have lost their lives in that war. And it is estimated that over 4,400 US military personnel have been killed, nearly 32,000 have been injured. It is also estimated the war has cost US tax payers at least $1.7 trillion over the past decade.
