A unique critique of the new economic and military imperialism of the United States and its allies in the twenty-first century. Inspired by the anti-globalization and anti-war movements, in which the author himself has played a crucial role, this is also an accessible introduction to the huge changes in global politics since the dominance of the American Empire with the end of the Cold War. It covers the key areas of the nature of the new imperialism; the economic power of the US; globalization and inequality; wars in the post Cold War era; oil and empire; and resisting the new imperialism. This lively, provocative and practical book is an essential guide to the politics of the new world order, which also offers constructive suggestions on how the global resistance movement should develop. It is important new reading for activists, students and all those wanting to understand and challenge the new imperialism.
