For over 25 years, Noam Chomsky's prolific political intervention has enlightened and inspired radicals whilst enraging their opponents in the halls of power. Beginning with a concise biography of his subject, Milan Rai presents a sympathetic yet probing analysis of Chomsky's critique of United States' media and foreign policy, and his vision of a libertarian socialist future. Drawing on the entire range of Chomsky's prodigious output, including little-known interviews and articles, this book examines Chomsky's assault on journalistic self-censorship and business control of the mass media. It shows how Chomsky challenges the US's view of itself as a defender of democracy and equal rights by uncovering the hidden motivations of its foreign policy makers. It draws out features of Chomsky's outlook which are sometimes obscured by a rapid coverage of a wide range of issues. In particular, the book emphasizes the importance of Chomsky's cultural critique in his ordering of political priorities.
