Indeed you can't ask before liberation, and they are free to dictate their future society through free and fair elections. Some people simply have a problem with America setting the initial state as a 'mini-USA' on the assumption that this will be best.
The reason I brought this up wasn't because I'm overly concerned about that particular issue (since, as has been said, free election enable the people to dictate their future, and it will take a hell of a long time to sort out Iraq anyway), but because it ties in with the original topic.
Why does the Arab world hate America? Because they have the view that America is 'winning'. Winning what? Well, I'll tell you
If you listen to most of the Arab feeling as it is reported in the media, you get the impression (that may well be false in terms of the general populace) that one aim of the fundamentalist Arab states and their populations is to turn the entire world into an islamic state. Indeed, we have Islamic extremists here in the UK who have expressed their aim of turning the UK into an islamic state.
On the flip side of the coin, by watching some of the actions America takes (including the leaking of a repost co-written by Chaney, I believe, that states it's intention to establish and maintain "USA total global domionance in all areas"), you get the impression that the USA wants to turn the whole world into a USA-esque state.
Now, clearly the USA is winning (mainly because capitalist policies based on free trade tend to be more popular than fundamentalist policies that result in lack of luxury for the populace), and the extremist Arabs can't stand this. In fact, they are in a rage that the world is slowly being turned into the diametric opposite of what they think it should be. The result? Jealousy. Jealousy leads to hatred.
That's my take on it.
