Fitness to lead, for me, is more about attitude than physical fitness.

Cabbies in London go through a process called "The Knowledge". Part of that process is a series of intensive interviews designed solely to weed out those applicants who are psychologically unfit to hold a licence (e.g. those who might lose their tempers and punch out a member of the public).

A similar process might be useful in keeping warmongers out of the Whitehouse and Westminster.
