Webster Griffin Tarpley is an activist and historian best known for his George Bush: The Unauthorized Biography (1992), a masterpiece of research which is still a must read. A decades-long expert on international terrorism, he directed the study Chi ha ucciso Aldo Moro? (Who Killed Aldo Moro?), commissioned by a member of the Italian government and published in Rome in 1978, which broke open the affiliation of the Red Brigades with the neofascist lodge P2.
