This weekend, Democracy Now! co-host Juan González gives the opening plenary at American University’s one-day conference, “Burying 200 Years of the U.S. Monroe Doctrine,” marking 200 years since the Monroe Doctrine, the foreign policy directive from President James Monroe that effectively declared all of Latin America a U.S. sphere of influence. For the past two centuries, the Monroe Doctrine has been repeatedly used to justify scores of invasions, interventions and CIA regime changes in the Americas. On today’s show, we speak to two other conference guests, CodePink’s Medea Benjamin and The Red Nation’s Nick Estes, about the Monroe Doctrine’s long and brutal legacy within U.S. imperialism.
