Israel went from being a symbol of the success of the labour movement to the personification of Western imperialism almost overnight. How was this possible? How could such a radical change occur in such a short length of time? Was it because of negligence within the Italian left resulting from a complex of excessive friendship towards the Jews and Israel? Has the analytical power within leftist political thought grown to shed new light on what was before veiled? It is difficult to believe that the presumed colonialist nature of Israel was not evident before the outbreak of the Six-Day War, just as it is not possible that the real nature of Zionism and the situation of the Palestinian victims were invisible prior to this event. Through an historical, political, and ideological investigation, this book explores this extraordinary, and multifaceted, phenomenon.
