published by the popular press who agree with Conquest's estimates are Stalin biographer Simon Sebag Montefiore, perestroika architect and former head of the Presidential Committee for the Rehabilitation of Victims of Political Repression Alexander Nikolaevich Yakovlev, and the director of Yale University's Annals of Communism series Jonathan Brent. Historian Dmitri Volkogonov, who was special adviser for defence issues to the Russian President Boris Yeltsin until 1994, is also broadly in agreement with Conquest. In 1997, Conquest stated: "We are all inclined to accept the Zemskov totals (even if not as complete) with their 14 million intake to Gulag 'camps' alone, to which must be added 4–5 million going to Gulag 'colonies', to say nothing of the 3.5 million already in, or sent to, 'labour settlements'. However taken, these are surely 'high' figures." In the preface to the 40th anniversary edition of The Great Terror (2007), Conquest wrote: "Exact numbers may never be known with complete certainty, but the total of deaths caused by the whole range of Soviet regime's terrors can hardly be lower than some fifteen million."
