Oh come on its a tad too simplistic to brandish Blair/Bush with the same brush as Hussain.
True, hundreds of thousands died in Iraq, but remember that the majority of the deaths were and still are at the hands of insurgents/millitia and not Western Troops.
Secondly, as wrong as Bush and Blair were, to suggest they were as bad as Hussain is actually quite disrespectful. Saddam directly ordered the killings of hundreds of thousands of people based on nothing other than ethnicity. He directly ordered the chemical bombing of innocent civilians. Then lets not forget the estimated 1million that died in wars that he led (Iran etc) + the estimated 200,000 additional civilians who died under his rule as a result the informant led state, kidnappings, gassing of whole rebel villages and the general awful standard of living.
True, Blair/Bush may have ordered the wrongful invasion of Iraq, but the events that followed were not much more than the results of war, which is and always has been complete and utter chaos. People got caught in the cross fire by accident . Saddam's Iraq was no accident. It was a planned Genocide. To compare them on a like to like basis simply shows your naivety of the situation.
Iraq is by no means paradise now, but its a hell of a lot better than it was 8 years ago.
