I am being entirely serious with this point; the transformation of Iraq from a Saddam-led totalitarian regime to a parliamentary democracy, and other examples including Libya or Egypt, was in part or a direct precipitant of Western intervention, whether through military or social means.
There is also the uncanny pattern of the US overthrowing democratically elected governments only to be replaced by dictatorships amenable to US interests. The motive for the US is clearly not just about whether a country's system of government is democratic.
