"An age-old civilization and its remnants have been destroyed.
A whole generation of Iraqi civilians has been killed, maimed and uprooted. Between 80,000 and 1.2 million are dead (depending on which estimate you go by). More than 4 million have been made refugees – half forced into exile in Jordan and Syria, and the other half internally uprooted."
This just has to be the largest catastrophe in the world in this decade, surpassing those of even the Darfur genocide, Afghanistan (which also involves the US) and even the great natural disasters like the Asian tsunami. The DR Congo might be the only one to rival it though.
