In a world that has returned to great power rivalry, understanding the grand strategy of these powers is crucial. This book introduces ten key terms for analysing grand strategy: simple, competitive, rational, allied, comprehensive, creative, agile, courageous, dirty, and proactive. Analysing both historical examples and current strategies, the book shows how the world’s great powers – the United States, China, Russia and the European Union (EU) – shape their strategic decisions today. Outlining the steps needed for a less confrontational grand strategy and a more peaceful and stable world order, this lively and accessible introduction, peppered with insights from world leaders, generals, and strategists, shows how the choices made in each of these ten areas will determine the course of international politics in the first half of the 21st century.
