I don't know, do you? I'm not sure it's something you can put a figure on But please don't try to make Blair out to be some sort of saviour, when his lies cost the lives of so many.
I'm trying to paint a fair and balanced viewpoint. We don't know how many, we do know that Saddam had the blood of at least 2.5mill people on his hand through his dictatorship. He murdered political dissidents, he ethnically cleansed Kurds, he murdered Shia's and oppressed them, he started a war with Iran that was absolutely brutal in terms of lives, and economic damage to the people of those two nations, he invaded a sovereign nation, he fired missiles at another, he used WMDs previously, he threatened to use them again, he set oil fields on fire creating major climate damage, I could go on.
The balanced view is yes, people died as the US and UK invaded Iraq, and far worse the power vacuum plunged the state downwards. But it's also absolutely clear that Saddam would have continued to use death, war, invasion and oppression had he remained in power.
The balanced view is that some lives were saved and some were lost by invading Iraq.
What is the view on the first gulf war? Should we have stayed out of it? Should we have pushed on and deposed him then? If we had removed him first time the Kurds wouldn't have been gassed to death. That is absolute proof that inaction has consequences in lives too. To ignore that is to not present a balanced viewpoint.
