The recent US intervention in Venezuela is a vivid demonstration of the new so-called ‘Donroe Doctrine’ asserting complete US supremacy in the western hemisphere. Paul, Luke, and Lizzy discuss the historical context of America’s new foreign policy stance and what it might mean for various neighbours including Brazil, Colombia, Mexico, Cuba, and Greenland. They also consider potential read across for Iran, Russia-Ukraine, and China-Taiwan, and whether it makes other conflicts more likely.
