Did the historical caesura of 9/11 represent a breaking point and a key driver in the evolution of pacifism in the United States? Starting from the aforementioned question and analyzing first-hand documents, the author reconsiders the evolution of the peace movement in the United States from the time immediately after 9/11 until the autumn 2002. Through only one year, the American citizens were in-volved in a series of dramatic challenges: 9/11, the war in Afghanistan and the Pa-triot Act. How was it possible to talk about peace in the aftermath of 9/11? Who did so? Which transformations characterized this new phase? Was the movement against war in Iraq rooted in the complex experience of the 2001 events? Working on a topic that has not yet been the object of rigorous historical analysis, the au-thor gives his answer to all these questions, focusing on the cases of Answer Coali-tion and Peaceful Tomorrows.
