Chomsky was first approached to write an op-ed column for the New York Times Syndicate on the first anniversary of the September 11 attacks on the basis of his highly influential volume 9/11 (2001). The international attention garnered by the subsequent column, entitled 9-11: Lessons Unlearned, convinced the publishers to commission Chomsky to write roughly 1000-words a month which they would then distribute as op-ed pieces. These are widely picked up overseas, but rarely in the United States and The New York Times itself never published them to its own readers. Internationally, the op-eds have appeared in the mainstream European press including The International Herald Tribune, The Guardian, and The Independent. Regional newspapers in the US that did pick up the op-eds were The Register Guard, The Dayton Daily News, and The Knoxville Voice. The first volume of these, collecting columns from September 2002 to March 2007, was published as Interventions (2007).
