He is the author of investigations into the extreme right-wing (particularly about the National Front Militias, which are the object of a parliamentary investigation and caused a separation of the extreme right-wing party), as well as into the Catholic Church (Opus Dei, for example).
Meyssan's book 9/11: The Big Lie (L'Effroyable imposture) challenges the official account of events of the September 11 terrorist attacks. In recent times, he published several stories claiming Donald Trump is the victim of a "campaign that has been scientifically organized against the President of the United States", orchestrated by the American administration establishment and the world intelligence community.
In 1994, Meyssan became a staff member of the Radical Party of the Left (PRG), a center-left political organization, and he participates in the campaign of Bernard Tapie (1994 European elections) and Christiane Taubira (2002 presidential elections).
From 1996 to 1999, he worked as substitute coordinator of the National Committee of Surveillance against the extreme right, which held weekly meetings with the 45 major political parties, unions and associations belonging to the French left-wing in order to draw up a common response to escalating intolerance.
Between 1999 and 2002, Meyssan replaced Emma Bonino in the leading post of the Anti-prohibitionist Radical Coordination, an international organization aiming to decriminalize drug use as a means to cut organized crime's main source of income.
Publication of The Big Lie
In 2002, he published a book on the September 11 terrorist attacks—9/11: The Big Lie—in which Meyssan argues that such attacks were organized by a faction of the US military industrial complex in order to impose a military regime. The book was translated into 28 languages.
His following book was Le Pentagate, a book arguing that the attack against the Pentagon was not carried out by a commercial airliner but a missile. The central thesis of the book is that a Boeing 757 did not hit The Pentagon. This was heavily criticised by other prominent 9/11 Truth Movement members such as Jim Hoffman.
He started a campaign at the United Nations to initiate an international investigation commission to revisit the general consensus regarding the 9/11 attacks, but he was not able to reach his objective. There was little support, except from the Arab League and the Gulf Cooperation Council.
In November 2005, Thierry Meyssan presided over the Axis for Peace 2005 Colloquium, which gathered over 130 participants from 37 nations in order to discuss the international situation and call a people’s mobilization in favour of international law and world peace and against the neoconservative trend.
Other areas of research
Meyssan also believes the Beslan massacre was thought out and perpetrated by the CIA, through the terrorist leader Shamil Basayev, who Meyssan insists was a CIA strawman. The purpose of the massacre in Beslan had been, claims Meyssan, an attempt by the USA to gain control of the resources of the Caspian Sea.
2011 Libyan civil war
This section needs expansion. You can help by adding to it. (August 2011)
On 22 August 2011, Meyssan while stuck at the Rixos Hotel in Tripoli, reported live, by voice, to the Russian television network RT (formerly known as Russia Today). He claimed that, contrary to other reports, Gaddafi forces had driven the rebels from most of the city. At the same time he described that he felt in danger, accusing other CNN and BBC journalists at the hotel of being spies from the CIA and the MI6, who were allegedly giving information on objectives to the NATO and the NTC militias.
That same day, Meyssan reported that U.S. agents, disguised as journalists at the Rixos hotel (as he had previously indicated) had marked him for assassination. He then stated that the identities of these spies would be released in due course. Five countries offered protection to Meyssan and Mahdi Darius Nazemroaya in their embassies, but they were unable to reach any of them, because of the heavy fighting around the hotel and the encirclement of some of those embassies by NTC militias
On 22 August 2011, the Battle of Tripoli code named Operation Operation Mermaid Dawn by the Libyan National Transition Council, commenced. Meyssan reported:
- Then, a NATO warship sailed up and anchored just off the shore at Tripoli, delivering heavy weapons and debarking Al Qaeda jihadi forces, which were led by NATO officers.
In the same report:
- NATO had been charged by the UN Security Council with protecting civilians in Libya. In reality, France and Great Britain have just re-started their colonial massacres.
