Historian Andrew Roberts is the author of more than a dozen major works of history, including Napoleon: A Life, Churchill: Walking with Destiny, and The Last King of America: The Misunderstood Reign of George III. His latest book, coauthored with General David Petraeus, is Conflict: The Evolution of Warfare from 1945 to Ukraine, which provides the basis for this interview. Roberts discusses the differences in the way nations and allied forces prosecute wars in the twentieth century vs. today. Roberts also discusses his strong support for Israel in the current conflict in Gaza both in the media and in the House of Lords, where  he is now a member. Roberts also explains (with some understandable exasperation) why Ridley Scott (the director of the recent film biography of Napoleon) is wrong —really wrong—when he says that historians are not to be trusted because “they weren’t there” when they describe historical events.
