Maduro, and Chavismo, are an episode, but the deep reasons for American interventionism have little to do with anything Hugo Chavez or Maduro did. It has to do with the Monroe Doctrine (and its revisions, including Trump's) and the needs of Imperialism. The USA can't have the international projection it has if their "back yard" is not "secured" first. That's why Latin American political thinkers, including conservative ones, have always signaled the US as a curse.
