These are some of the nicknames used by US officials for leaders around the world:
- French President Nicolas Sarkozy: 'Emperor with no clothes'
- Italian PM Silvio Berlusconi: 'Feckless, vain and ineffective as a modern European leader'
- Russian President Dmitry Medvedev: 'Plays Robin to Putin's Batman'
- Russian Prime Minister Vladimir Putin: An 'Alpha Dog'
- Iranian President Mahmoud Ahmadinejad: Like 'Hitler'
- North Korean dictator Kim Jong-il: 'Flabby old chap'
The accounts of Turkish Prime Minister Recep Tayyip Erdogan were suspicious of him, while remarks about Kenya's leadership were contemptuous.
One exchange indicated the State Department in Washington asked the US embassy in Rome to check rumours that Prime Minister Silvio Berlusconi had private property dealings with Putin. Russian President Dmitry Medvedev was termed "pale, hesitant".
In an assessment of German Chancellor Angela Merkel, a diplomat marked her: "Avoids risk, not very creative."
German news weekly Der Spiegel -- copies of which went on sale in railway stations hours before an embargo imposed by a consortium of news media was due to run out -- said 90 per cent of the material involved the period from 2005 onwards. Only six per cent was labelled "secret".
