But instead of going from Vienna to Israel he went further to the United States where he arrived in April 1978 and there subsequently continued his studies. He graduated from Brandeis University and earned his PhD in history from Rutgers University.

Career
Felshtinsky has published a number of books on the history of the Communist movement. In one of those books, Leaders the Mobsters, he described the Bolshevik party as a Mafia-like organization where "almost no one died by a natural cause,". According to Felshinsky, the list of assassinations includes poisoning of Vladimir Lenin, Felix Dzerzhinsky, and Maksim Gorky by Genrikh Yagoda on orders from Joseph Stalin, murders of Mikhail Frunze, Vyacheslav Menzhinsky, and Leon Trotsky, and the poisoning of Stalin by associates of Lavrentiy Beria. In 1998, Felshtinsky traveled back to Moscow in order to study the politics of contemporary Russia. At that time, he became acquainted with Alexander Litvinenko, a lieutenant colonel of the Federal Security Service. In 2000, Felshtinsky and Litvinenko began working on Blowing Up Russia, a book that describes the gradual appropriation of power in Russia by the security apparatus and details the FSB's involvement in a series of terrorist acts that took place between 1994 and 1999. In August 2001, several chapters from Blowing Up Russia were published in a special edition of the newspaper Novaya Gazeta. In 2002, the book became the basis for a documentary film, Blowing Up Russia. Both the book and the documentary were officially banned in Russia for "divulging state secrets". Until 2006, Felshtinsky continued working with Litvinenko on gathering additional materials documenting the FSB's involvement in the apartment house bombings of September 1999 According to authors, the bombings were committed by the Russian Federal Security Service, as a false flag operation intended to justify the Second Chechen War. In November 2006, Litvinenko died in London of acute radiation syndrome, three weeks after being poisoned with polonium-210.. In 2007, investigator Mikhail Trepashkin said that, according to his FSB sources, "everyone who was involved in the publication of the book Blowing Up Russia will be killed," and that three FSB agents had made a trip to Boston to prepare the assassination of Felshtinsky. After the death of exiled oligarch Boris Berezovsky, who sponsored the book, Felshinsky suggested that Berezovsky was killed.
