Meyssan is president of the Voltaire Network, which had been a respected independent think tank prior to the publication of 9/11: The Big Lie. His reputation helped raise his conspiracy theory to prominence.[2]
Meyssan has been noted as using cross-citations of other conspiracy theorists' works in order to lend the appearance of credibility to his ideas. Regarding the events of 9/11, Meyssan cited Webster Tarpley; Tarpley cited David Ray Griffin; and Griffin cited Meyssan.[3]
In 2002, he published a book on the September 11 terrorist attacks, with the English translation titled 9/11: The Big Lie. Meyssan argued that the attacks were organized by a faction of the US military–industrial complex in order to impose a non-democratic regime in the United States and to extend US imperialism.[4] It is one of "the first wave of book-length conspiracy speculations" in France and Germany about 9/11.[5]
A follow-up to his first book titled L’effroyable Imposture II (The Big Lie 2) accused Israel of carrying out the assassination of Rafic Hariri.
