If communication is the key to an open society, then WikiLeaks has done its job! The release of the documents is an embarrassment for the United States of America and in the future foreign powers will be most reluctant to express honest opinions when dealing with it.
The North Koreans may be feeling a little more paranoid today, with the revelations that China, its only friend in the world, consider it a "spoilt child" and would be happy for reunification with South Korea. As China is the only country with real influence over the rogue state, it would be dangerous for the world if their special relationship was to end.
As for the revelations about our own Prince Andrew, the man is such an arrogant over-bearing, cossetted spoilt brat, that any negative comments about him would be like water off a duck's back. The Ambassador who wrote the remarks, Tatiana Gfoeller, stated that the prince spoke "cockily" and "verged on the rude" at a 2008 meeting in Kyrgyzstan with British and Canadian business leaders. Just being his normal self then!
The prince was there in his capacity as Special UK trade representative, a position which allows him to indulge in his love for fast cars, luxury air-flights, endless rounds of golf and royal belligerence, as to the palace born.
Most people in the UK see the prince as a porky parasite, with absolutely no empathy for those he purports to represent on the world stage. He is likely to be totally unconcerned by any negative remarks about him.
