Whilst looking around on the BBC's iPlayer I came across this programme on Richard Nixon.
Titled 'Nixon in the Den' it is a look at the rise and fall of the 37th President of the United States. In it, historian David Reynolds argues that the traits that brought him to the very top - his steely ambition, excruciating work ethic and a deep-seated inferiority complex - also fuelled his eventual downfall.
The portrait painted is of a man who achieved great things - a thaw in relations with Russia and China and an end to the Vietnam War - but never seemed able to relax and enjoy his successes.
It's available until next Sunday (20th) and is well worth a watch.
