I think this book is interesting and important reading material for those who want to understand what is happening nowadays, and why USA "can't go it alone".
Nye says, among other things, that the world is no longer the realm of an unipolar power (USA). According to him, it is necessary to distinguish three dimensions of power.
The first dimension is interstate military issues, and it is dominated by USA. We can say that this dimension of power is unipolar. However, there are other dimensions: the economic one, and the dimension regarding transnational issues.
The economic dimension of power deals with interstate economic issues, and has many important actors (for example the EU, Japan, and other relevant players). Nye highlights the fact that this second dimension is multipolar: USA needs the cooperation of other states, in order to achive its objectives.
Finally, the third dimension takes into account transnational issues such as global warming and and terrorism. In this case the structure of power is disperse, and the number of relevant state and nonstate increases exponentially.
Joseph Nye Jr. points out that the importance of the military dimension, that involves hard power, is likely to diminish in the future. On the other hand, he predicts that the relevance of the other two dimensions, more soft power oriented, is going to increase, due to many factors (for example, the information revolution). However, a state has to take into account not only soft power but also hard power in order to achieve success in its policies.
The author tries to make the idea of the three dimensions of power more easily understandable by comparing power to a three-dimensional chessboard, where you have to play in the three dimensions if you want to win. The problem, according to him, is that USA is increasingly paying attention only to the military dimension of power, and due to that it is likely to have more than a few problems in the long term. A onedimensional player in a three dimensional game can only lose...
On the whole, I believe that this a very good book that can help you to understand better what is happening today ... Recommended !!!
