Francis Fukuyama perfectly expresses the difference between freedom and democracy:

... the desire to live in a modern society and to be free of tyranny is universal, or nearly so ... each year [millions of people] move from the developing to the developed world, where they hope to find the political stability, job opportunities, health care, and education that they lack at home.

But this is different from saying that there is a universal desire to live in a liberal society - that is, a political order characterised by a sphere of individual rights and the rule of law. The desire to live in a liberal democracy is ... acquired over time, often as a byproduct of successful modernisation ...

The Bush administration seems to have assumed ... that both democracy and a market economy [are] default conditions to which societies [will] revert once oppressive tyranny [is] removed ...

Long before you have a liberal democracy, you have to have a functioning state (something that never disappeared in Germany or Japan after they were defeated in the second world war). This is something that cannot be taken for granted in countries like Iraq.
