At ninety, Noam Chomsky remains one of the most persistent, active and lucid voices among left-wing intellectuals in the contemporary world. Global upset brings together twelve interviews in which the tenacious activist reflects on what he considers the most pressing and urgent issues in the international sphere, tracing a punctual, erudite and uncompromising radiography on the world that we are leaving as inheritance to our grandchildren, at risk in the face of threats such as climate change or the new nuclear arms race.

In the interviews included in this new book, Chomsky examines the latest events that take place around the globe: the rise of the Islamic State, the scope of the police state that has gradually been implemented in cyberspace, social unrest in the face of economic policies - like those emanating from the Troika in Europe - that widen the gap of social inequality, conflicts in the Middle East and, of course, Donald Trump's rise to the presidency of the United States. On more personal notes, he also addresses his own childhood in Philadelphia - the relevance to his formation of a second-hand bookshop in the New York of the thirties, before he turned ten years old - and his career until he became a dissident United States number one and the establishment.

Given the inability of the system to manage the threats it generates, argues Chomsky, it is in our hands to raise awareness to begin a radical change through the smallest and everyday gestures.
