Robert Kagan makes the case for continued leadership of the U.S as a champion of liberal democracy and free trade, as the view that it will just happen in a multipolar world of China, India, the U.S. and Europe, is not credible. The existing democracies- India, Brazil, Turkey, S. Africa, Australia -are weak and lack the experience to provide this leadership. India and China could easily end up in rivalry in a multipolar world. This has implications for today. The U.S. cannot provide this leadership as a services economy- it needs a strong manufacturing base to do this. Lessening inequality was a hallmark of the progress made in the 20th century, and especially the six decades since World War II when the U.S. clearly exercized this leadership. The progress to European unity was another hallmark of these six decades. A healthy Japan was also part of this.
