Late last year, a conflict that had lain almost dormant for more than 25 years flared up again. Armenia and Azerbaijan clashed over the disputed territory of Nagorno Karabakh, with Azerbaijan ultimately reclaiming much of the land they had lost in the conflict of the 1990s. More than 6000 people were killed, and thousands more were driven from their homes. So who really won? And what now for those whose lives were turned upside down during 44 days of fighting? With rare access inside Nagorno Karabakh, Jonah Fisher travels to both Azerbaijan and Armenia. He meets those who won their homes back and those who lost their loved ones - and discovers that a much bigger power is making a comeback.
