On Start the Week Andrew Marr talks to historian Niall Ferguson about his biography of Henry Kissinger. Reviled and revered in equal measure Kissinger was the statesman at the heart of American foreign policy for decades, and Ferguson argues that far from being a Machiavellian realist he was driven by idealism. Jane Smiley's trilogy of novels chart a hundred years of American life through the lives of one family. She shows clearly how the big political and social upheavals of the time were reflected in the day-to-day. The personal and political come together in the extraordinary diaries of Ivan Maisky, the Russian ambassador to London before WWII. Gabriel Gorodetsky has compiled the diaries which document Britain's drift to war during the 1930s. Producer: Katy Hickman.
