Jews and often conjure up anti-Semitic canards, making them popular with fringe publications on both the left and the right. Like many other contemporary anti-Semites, Roberts frames his anti-Semitism as criticism of Israel and the country’s supporters. His published views, however, go far beyond any criticism of Israel’s policies, regularly charging Israeli or Jewish control of the U.S. government and media and comparing Israel to the Nazi regime. In 2003, the Southern Poverty Law Centre wrote that Roberts was a key figure in the mainstreaming of the antisemitic "cultural Marxism" conspiracy theory. In 2016, antisemitism researchers Manfred Gerstenfeld and Leah Hagelberg wrote about him sharing antisemitic conspiracy theory material about Israel creating ISIL. Roberts has described himself as a "9/11 skeptic" and spoken at 9/11 Truth movement events. Regarding the assassination of John F. Kennedy, Roberts has written that "all evidence pointed to a plot by the Joint Chiefs, CIA, and Secret Service whose right-wing leaders had concluded that President Kennedy was too 'soft on communism'". He has also stated that the Charlie Hebdo shooting has many of the characteristics of a false flag operation" motivated in part “to stifle the growing European sympathy for the Palestinians and to realign Europe with Israel”. The Washington Post noted that in 2014 Roberts speculated on his blog that Ebola originated as a US bioweapon and this was picked up by North Korea's state media. Views on World War II and the Holocaust In 2019, Roberts wrote in support of the views of Holocaust denier David Irving, asserting that "Irving, without any doubt the best historian of the European part of World War II, learned at his great expense that challenging myths does not go unpunished... I will avoid the story of how this came to be, but, yes, you guessed it, it was the Zionists". Roberts added that "No German plans, or orders from Hitler, or from Himmler or anyone else have ever been found for an organized holocaust by gas and cremation of Jews... The "death camps" were in fact work camps. Auschwitz, for example, today a Holocaust museum, was the site of Germany's essential artificial rubber factory. Germany was desperate for a work force." Personal life Roberts' wife, Linda, was born in the United Kingdom and professionally trained in ballet. The couple met while he was at the University of Oxford.
