Normally western democracy promotion is about artificially implanting democracy into a country, in order to take control of it. Present day Iran appears to be an example of this. Or a democratic government could be replaced via a coup, and then resume democracy under the coup leaders.
However, in the case of the Turks and Caicos Islands, on August 2009, democracy was taken away from the TCI Belongers by the UK in order to control the Islands.
