also been one of the leading critics of Viktor Suvorov, who has argued that Barbarossa was a "preventative war" forced upon Germany by Stalin, who according to Suvorov was planning to attack Germany later in the summer of 1941. Later work In his book Democracy and Populism: Fear and Hatred (2005), Lukacs writes about the current state of American democracy. He warns that the populism he perceives as ascendant in the United States renders it vulnerable to demagoguery. He claims that a transformation from liberal democracy to populism can be seen in the replacement of knowledge and history with propaganda and infotainment. In the same book, Lukacs criticizes legalized abortion, pornography, cloning and sexual permissiveness as marking what he sees as the increasing decadence, depravity, corruption and amorality of modern American society. June 1941: Hitler and Stalin (2006) is a book-length study of the two leaders with a focus on the events leading up to Operation Barbarossa. George Kennan: A Study of Character (2007) is a biography of Lukacs' friend George F. Kennan, based on privileged access to Kennan's private papers. Blood, Toil, Tears and Sweat (2008) is a continuation of his work on what Lukacs considered the greatness of Churchill. Last Rites (2009) continues the "auto-history" he published in Confessions of an Original Sinner (1990). The Future of History was published on 26 April 2011. In A Short History of the Twentieth Century (2013), Lukacs attempts to challenge the idea (common to both professional historians and experts in international relations) that the Cold War presented a bipolar system or a major strategic rivalry or conflict, instead arguing that the 20th century was one of American dominance. Citing the biographical example of Hitler as well as left- and right-wing populism in the United States, Lukacs also argues in the book that populism was the most destructive force of the 20th century and attempts to disentangle the concept of populism from its frequent (though, Lukacs argues, inaccurate) conflation with the inherent stances of left-wing politics. Private life In 1953, he married Helen Elizabeth Schofield, the daughter of a Philadelphia lawyer; the couple had two children. His wife died in 1971. He married his second wife, Stephanie Harvey, in 1974. From this marriage, Lukacs had step-children; his second wife died in 2003. He married for a third time, but his marriage to Pamela Hall ended in divorce. After his retirement in 1994,
