The Academy of Ideas team – Alastair Donald, Claire Fox, Rob Lyons and Jacob Reynolds – discuss the immediate fallout after President Trump's decision to capture Venezuelan President Nicolás Maduro.Why did Trump act? Is it about narcotics, oil, democracy or his desire to create a 'Don-roe doctrine' of US dominance in the Americas?What has been the role of domestic politics – is this the culture wars by other means?For those who believe in that sovereignty is a vital right for nation states, should we make an exception here given the appalling nature of Maduro's regime or must sovereignty be defended at all times?What's left of the 'rules-based international order' when Trump is not only intervening in Venezuela but threatening Denmark's control of Greenland, too?Will the reaction against Trump's actions weaken the hand of populist forces elsewhere?
