Acclaimed historian Niall Ferguson ranges across the entire history of America's foreign entanglements and delves into all the dimensions of American power—military, economic, cultural, and political. The result is a book whose conclusions are as convincing, and troubling, as they are original. Ferguson demonstrates that America has always been an empire in denial and shows the fateful consequences of its special brand of imperialism. He examines the challenges to the United States from its principal rivals, the European Union and China, and offers a compelling analysis of the connection between the country's domestic economic health and its foreign affairs—the bottom line of imperialism, American style. Colossus is a peerless reckoning with American power that should be read by any thinking citizen of this unspoken empire.
