On April 6, 2013, a panel on “What is Imperialism? (What Now?)” took place during the Platypus International Convention at the School of the Art Institute of Chicago. The panel was motivated by the ten-year anniversary of the U.S. invasion of Iraq and aimed to discuss whether we are any closer to understanding what imperialism is and the relationship between anti-imperialism and anti-capitalism. This panel brought together Larry Everest from the Revolutionary Communist Party (USA), Joseph Green from Communist Voice, and James Turley of the Communist Party of Great Britain, and was moderated by Lucy Parker of Platypus. What follows is an edited transcript of the conversation.
