Context

The book mentions that Dulles play a vital role in leading the US into the Vietnam War, and assisting to overthrow cold war governments such as Guatemala, Iran, the Congo, and Indonesia.[3]

The book's first several chapters give information about the family background, childhoods, and college educations of the two brothers. In this way, some points of their personal life are provided: Foster was a devoted husband while Allen was an unfaithful husband. Kinzer explains how the actions of the Dulles brothers aimed at removing world leaders whom they considered dangerous to the American interests. The brothers had a significant effect on the United States foreign policy and global conflicts. [5]

The book mentions "six monsters" that the "Dulles brothers believed had to be brought down": Mohammed Mossadegh in Iran, Jacobo Árbenz in Guatemala, Ho Chi Minh in Vietnam, Sukarno in Indonesia, Patrice Lumumba in the Congo, and Fidel Castro in Cuba. Ho Chi Minh and Castro espoused left-wing politics. The other leaders on the list were nationalists who campaigned for their country's independence. The book also discusses Iran at length. While explaining the careers of the brothers, Kinzer describes events from American history such as mind-control experiments “in which psychoactive drugs were administered to unknowing victims.”
