Amid all this, it's easy to forget that while the British military mission ended in 2009, the legacy of the war is still being played out to this day, with millions of Iraqis, injured servicemen and relatives of those killed continuing to suffer.
According to a 2007 interview with Antonio Guterres, the then-U.N. High Commissioner for Refugees, there were nearly 2 million Iraqi refugees who had fled their country, and another 1.7 million were internally displaced. Since the end of the war the situation has not improved owing to continued instability and the rise of Islamic State.

Ali Ismail Abbas, 12, wounded during an airstrike according to hospital sources, lies in a hospital bed in Baghdad, April 6, 2003. Abbas was fast asleep when war shattered his life. A missile obliterated his home and most of his family, leaving him orphaned, badly burned and blowing off both his arms. "It was midnight when the missile fell on us. My father, my mother and my brother died. My mother was five months pregnant," the traumatised boy told Reuters at Baghdad's Kindi hospital. "Our neighbours pulled me out and brought me here. I was unconscious," he said.
Without doubt, those who suffered most in the Iraq war were Iraqi civilians who are still dying in huge numbers to this day. Just this Sunday at least 160 were killed in a suicide bombing in Baghdad carried out by the so-called Islamic State.

So-called Islamic State grew out of the power vacuum left in the wake of the Iraq War and spread - physically - to neighbouring countries and - ideologically - across the globe. This number does not include those killed in Syria or by worldwide terrorist attacks for which the group has claimed responsibility.

The Islamic State (IS) jihadist group executed hundreds of mostly Shiite recruits last June in what is known as the Speicher massacre, named for the military base near which they were captured. Thirteen grave sites have been found - 10 in the palace complex and three outside.
According to the Congressional Research Service, 1,645 American soldiers suffered either "the loss of one or more limbs, the loss of one or more partial limbs, or the loss of one or more full or partial hand or foot".
