at the request of Di Pietro - to join instead the PSE group (Party of European Socialists) as an independent member. In Italy he created the group Cantiere per il Bene Comune (Construction of the Common Good) together with Achille Occhetto, Paolo Sylos Labini, Elio Veltri, Antonello Falomi and Diego Novelli. In October 2004 I peggiori crimini del comunismo (The Worst Crimes of Communism) was published, co-written by Chiesa and the cartoonist Vauro, a biting satire which reveals the leftist past of some of the closest associates of the current Prime Minister of the time, Silvio Berlusconi. In 2005, a book of interviews was issued, edited by Massimo Panarari, entitled Cronache Marxziane (Marxian Chronicles), translated a year later into Russian with the title Vostok-Zapad:Voinà Imperii. In the same year, a collection of essays was published called Prima della tempesta (Before the Storm). In 2007, Chiesa produced two volumes: Le Carceri segrete della CIA in Europa (The Secret Prisons of CIA on EU soil) - co-authored by him and two of his closest collaborators, Francesco De Carlo and Giovanni Melogli – and Zero: Why the Official Version About 9/11 is a Fraud, co-authored by him and many other writers and edited by another of his collaborators, Roberto Vignoli. The contributions of Chiesa to this collection are the Introduction and a long essay on geopolitics called Europa, perché Marte ha sconfitto Venere (Europe: Why Mars Defeated Venus). In October 2007, the Movie Zero: inchiesta sull'11 settembre (Zero: An Investigation into 9/11) was presented at the International Movie Festival of Rome. It was created by a group - promoted by Giulietto Chiesa - led by Paolo Jormi Bianchi and was directed by Franco Fracassi and Francesco Trento. It began to be distributed from the beginning of 2008. Following a version of the "inside job" 9/11 conspiracy theory, it suggests that officials inside and outside the US Government were directly involved in planning and executing the attacks. In an interview with Press TV, Chiesa stated that the attacks involved a calculated conspiracy implicating US, Israeli, Pakistani and Saudi secret services. On 12 September 2008, Zero was broadcast by Russian Channel 1 television, achieving an extraordinary success in terms of audience. Over thirty million people watched the movie. The movie was deeply debunked in the book "Zerobubbole" (in Italian) by a group by Italian and international experts. The book is freely available on the Internet.
