It is one thing to denazify a "modern western country" that shares most of your values, culture and religion, and that has had institutions for some time. It is another thing altogether to pull off the deal in a country that has never had a working civil society, civil institions, education, etc. Especially if you do not share it's culture or religion, and there is a part of the country that is still actively engaged in a military campaign to obstruct you.

Not saying that it couldn't be done, or that mistakes weren't made. Just that you can't compare the two like that.

Both Japan and Germany had some semblance of democratic institutions, but they were taken over by authoritarians, often using violence:

Iraq had some history, pre-Sadam, and that seems to be returning:

Afghanistan has had little of it in the last few decades (since at least the Soviets rolled in), and much less in the more rural regions.

There's a difference between rebuilding institutions and creating (perhaps from scratch) a civil society.
