Some countries can't have democracy. They are only fit to be ruled by a iron-fisted dictator or tyrant like Ghaddafi.
If democracy is forcefully imposed by some foreign power as is the case of Iraq or Afganistan the results are not good as that is not really democracy but can be termed as colonization by a foreign power!
They will put their own stooge against other beast like local candidates who can't garner enough votes which will ensure victory for the American stooge.
