This revised fifth edition of the bestselling Diplomacy, from globally renowned thinker and scholar in diplomacy research and teaching Geoff Berridge, takes into account crucial developments and shifts on the global stage in the last 5 years. At the heart of diplomacy, and a central theme of this book, is the art of negotiation. As well as involving choice of its most promising channels, this includes how to sustain momentum via a deadline, for the consequences of not settling by midnight on the clock of the talks usually concentrates minds. The examples included, such as the Iran nuclear talks, are mostly contemporary, but historical background to the diplomatic methods themselves is always provided. This helps to show that a rejuvenation of key features of traditional diplomacy has occurred in recent years that has gone largely unnoticed, partly because new labels have been given to old procedures, a notable instance being the rebranding of propaganda as 'public diplomacy'. Fully updated, new case studies explore lessons of the 2014 G20 summit in Brisbane, and those of the highly topical Budapest Memorandum on Ukraine. Berridge's comprehensive and invaluable text also includes new chapters on secret intelligence and economic and commercial diplomacy.
