WW I – Kaiser Wilhelm, WW II – Hitler, Cold War – Stalin, Gulf war – Saddam Hussein, the lesson is clear, even Gaddafi had a weedy little moustache, but that was only a minor conflict. Analysts in the CIA are now looking carefully at Putin’s upper lip for any signs of a fledgling growth. The danger for intelligence agencies is that there is not a 100% confidence in using this indicator. Kruschev nearly started WW III and he was clean shaven, though on occasions did have a bit of stubble.
As yet psychologists are unsure why megalomaniacs need the reassurance of a moustache.
Researchers at the Harvard Department of Facial Hair have noted that:
Dictators usually opt for very neat trimmed moustaches, probably an indicator of a need for control or an obsessive compulsion.
Modern terrorists tend to go for damn great ragged beards and regard anyone without a beard as rather sissy.
Revolutionaries, such as Guevarra and Castro, as distinct from conventional terrorists, have grown large bushy beards, but this may be due to the difficulties of shaving in the jungle.
Art critics, book reviewers and pseudo intellectuals frequently have beards to show their unconventional side, but do not usually become involved in violence.
