In both Bilbao's and Torres Caicedo's works, the Mexican–American War and Walker's expedition to Nicaragua are explicitly mentioned as examples of dangers for the region. For Bilbao, "Latin America" was not a geographical concept, since he excluded Brazil, Paraguay and Mexico. Both authors also ask for the union of all Latin American countries as the only way to defend their territories against further foreign U.S. interventions. Both rejected also European imperialism, claiming that the return of European countries to non-democratic forms of government was another danger for Latin American countries, and used the same word to describe the state of European politics at the time: "despotism." Several years later, during the French invasion of Mexico, Bilbao wrote another work, "Emancipation of the Spirit in America," where he asked all Latin American countries to support the Mexican cause against France, and rejected French imperialism in Asia, Africa, Europe and the Americas. He asked Latin American intellectuals to search for their "intellectual emancipation" by abandoning all French ideas, claiming that France was: "Hypocrite, because she calls herself protector of the Latin race just to subject it to her exploitation regime; treacherous, because she speaks of freedom and nationality, when, unable to conquer freedom for herself, she enslaves others instead!" Therefore, as Michel Gobat puts it, the term Latin America itself had an "anti-imperial genesis," and their creators were far from supporting any form of imperialism in the region, or in any other place of the globe.
