LONDON -- The final indignity, if you are an Iraqi who was shot for accidentally turning into the path of a U.S. military convoy (they thought you might be a terrorist), or blown apart by a car bomb or an airstrike, or tortured and murdered by kidnappers, or just for being a Sunni or a Shiite, is that U.S. President George W. Bush and British Prime Minister Tony Blair will deny that your death happened. The script they are working from says (in Bush's words last December) that only "30,000, more or less" have been killed in Iraq during and since the invasion in March, 2003.

So they have a huge incentive to discredit the report in the British medical journal The Lancet last week that an extra 655,000 Iraqis have died since the invasion in excess of the natural death rate: 2.5 percent of the population.

"I don't consider it a credible report," said Bush, without giving any reason why he didn't.
