The return of the series presented by Barry Cunliffe. Fifty years ago Nazi Germany attacked Soviet Russia. So began what Lord Bullock describes as 'the longest and most intensive and brutal conflict between two nations in history.' He discusses the parallel lives of the greatest tyrants of the 20th century - Adolf Hitler and Josef Stalin. Also, Christopher Cviic focuses on the current political turmoil in Yugoslavia, deeply rooted in history, and tells John Miller why the country seems to be falling apart. Producer John Knight
