Isaias Afewerki, Eritrea's president, led his country to independence in a decade-long war with Ethiopia.
Today he tolerates neither opposition nor dissent as he increasingly isolates his nation of five million people from the outside world.
Journalist Sinéad O'Shea travelled undercover to Eritrea and found that its focus on security and isolation is borne of bitter experience.
Many Eritreans believe that if Ethiopia were to make another attempt to capture its strategic Red Sea coastline, the rest of the world would turn a blind eye.
Accessing Iran's border region
In part two, People & Power gains rare access to Iran's remote and dangerous border region looking at the roots of the Jundollah, a group which says it is fighting for the rights of the Baluch people in southeastern Iran.
In November, 15 members of Iran's elite Revolutionary Guards and 27 others died in a suicide bombing which was carried out in Iran's Sistan-Baluchestan province, and was one of the deadliest attacks on the powerful unit in recent decades.
The Jundollah claimed responsibility for the attack, and is thought to be hiding in neighbouring Pakistan.
Iran believes the group is funded and backed by the US, the UK and Pakistan. Nazanine Moshiri reports for People & Power.
This episode of People & Power aired from Wednesday, December 2, 2009.
