he operation that led to the abduction of Nicolas Maduro fits into the long history of US foreign policy in Latin America. Donald Trump dispensed with the usual humanitarian veneer that typically accompanies American interventionism. But the real surprise lay in the fact that this intervention contradicted some of the ideas held by the Trumpist movement. That movement has been divided over the assertion of an openly imperial ambition by the president.

A significant number of intellectuals who praised Trump's electoral victories are backers of isolationism. This doctrine holds that the US should refuse to play an active role in world affairs. According to its proponents, foreign policy should be limited to defending the borders, especially against immigration.

This isolationism has deep roots in American political tradition. John C. Calhoun (1782 – 1850), the seventh vice president and a key theorist of Southern ideology, is its historical figurehead. Calhoun, who was opposed to a strong federal government, justified maintaining slavery in Southern states by asserting that they could legally refuse to apply federal laws adopted by the majority in the North.

Calhoun therefore opposed the Mexican-American War (1846-1848), which resulted in the forced cession of territories that today form the southwestern US. His opposition rested on two arguments: that territorial expansion risked turning the Union into an imperial power, and "the incorporation of Mexico" would threaten "the government of the white race." This anti-imperialism was based on the idea that it was impossible to pursue an interventionist policy while maintaining a political order founded on white supremacy.
