The papers document several aspects of the Pinochet era in Chilean politics. Cubillos Sallato's tenure as Chilean foreign
minister included negotiations between Argentina and Chile after a severe dispute developed between the two countries over
the Beagle Channel. An end to the conflict, which verged at times on warfare, was mediated by Pope John Paul II. Cubillo Sallato's
position as cabinet minister meant that he was also near the center of decision making on other matters under Pinochet, including
the wholesale adoption of free market economic principles. In doing so, the Chilean government followed policies prescribed
by Milton Friedman and his fellow economists on the faculty of the University of Chicago. Cubillo Sallato played an important
role in fostering this process, and knew many of the key players.
