I see that the lancet is now estimating that about 650,000 extra deaths may have taken place since the war in iraq began.
This is a controversial figure, as its much higer than previous esitmates, but it uses a statistical approach that has been used in many other countries, so in theory it should be reasonably accurate.
The margin of error is pretty large: 390,000 to 900,000. But even the lower figure is pretty huge.
Infact, even the lower figure is more than saddam is thought to have killed in his 24 years in power.
(unless you include the 500,000 killed in the war with iran.. but we supported that didn't we?)
Apparently we are likely to need current troop levels in iraq until 2010.
