What, "stop the economic sanctions, stop the bombings and send large wads of cash to democratising organisations and pro-human rights groups within Iraq" Isn't specific enough for you?

It's hardly a "generalisation". It's practically a blueprint.
As for your claim that it wouldn't have "realistically worked"... Sheer nonsense. Why wouldn't it have worked? There are many historical examples of oppressive regimes being overthrown through popular struggle throughout history. You've got the British being thrown out of India, Indonesia's overthrow of the horribly violent, US/UK supported Suharto regime... and many more.
So why wouldn't it work in Iraq? Do you have ANY reasons to back this claim up? At all?
