The history of U.S. relations with Latin America is a story of imperialism, exploitation, and crimes against humanity. Eduardo Galeano’s book, “Open Veins of Latin American,” is an excellent introduction to this history. Greg Grandin’s 2006 book, “Empire’s Workshop,” and Naomi Klein’s more-recent book, “The Shock Doctrine,” cover issues of modern economic and military imperialism in the region. From the Monroe Doctrine to the School of the Americas, the tax dollars of U.S. citizens have been used to sell arms to cruel militias, install and uphold brutal dictators, train anti-communist insurgencies in torture methods, implement trade policies that increase extreme poverty and inequality, and undermine democratic movements. But there are hopeful signs on the horizon.
