>>Because of the sanctions in the 90's there were also up to half a million excess deaths of children aged under 5
Saddam wanted to get rid of the sanctions, it was in his direct interest to inflate the statistics. (There were reports of e.g. multiple funerals for a given dead child, too.)
His regime also had "extra" income from smuggling, which could have been used to alleviate suffering of civilians under his boot. These resources weren't used for that, as far as I've read.
I never got a good answer to my standard point, when this was a hot subject:
It is arguably bad to give in to extortion from dictators. In this case a dictator isn't using his resources to alleviate the suffering of civilians in his own country!
To let dictators get their will through by the suffering of their own civilians is obviously a very, very bad precedent.
