I would argue that not every society will thrive under a democracy. The people must be somewhat educated, politically savy, considerate, and accommodating. At least this has to be true in the beginning of a democracy where the people are laying the foundations.

Now I agree that the policies of the United States may not always be in the interest of the people from that part of the world, but a "mild" dictator like the one that the Saudi Arabia has or the one that Turkey has right now, these are better models sometimes. The SA of 50 years ago had no notion of human rights and severely under developed and could in no way support a democracy. Of course a dictatorship is not ideal, and the people of SA will have to pay a terrible price for it some day, but for now a dictatorship that "bows" to the west is not the worst thing either.
