Allan Little analyses four parts of the world where the 'tectonic plates' of history keep bringing the regions into the news headlines generation after generation.
Allan reported from Sierra Leone in the 1990s, during the bleakest times of the conflict that engulfed the country.
Now he returns to examine some of the reasons why a place that offered promise at Independence descended into such chaos and brutality.
Colonial rule, insufficient preparation for Independence and a structure that allowed dictators to emerge, all played a part.
But he finds a new realism and determination, too.
In candid and revealing interviews, he talks to those who feel their country must move on from being a 'victim of colonialism' and take responsibility for its own future.
