"Full-blooded democracy still remains a brave new experiment, the history of ancient Athens notwithstanding. It would be unwise to assume that its victory across the globe is inevitable, for democracy is not always a simple mode of governing. It is almost forgotten that one reason why in this century the world stood three times on the verge of chaos - during two world wars and one world depression - was that the leading democracies were almost as prone to accidents and blunders as were their authoritarian rivals."
