Robert Service, a senior fellow at the Hoover Institution and a fellow of St Antony’s College, Oxford, is a noted Russian historian and political commentator. In his recent book, Spies and Commissars, Service tells an unconventional and riveting story of the Russian Revolution, looking beyond official government documents to the worlds of business, journalism, and espionage to see how the West interacted with the new Bolshevik government. Service notes that Hoover’s huge food and humanitarian missions in 1919 “probably did save Europe from the Bolsheviks,” but, he asks, did Britain save the Bolshevik revolution at a time when it might have crumbled?
