The Limits of Power: The End of American Exceptionalism

So I was researching into presidential candidates, and in the debate, I found that "American Exceptionalism" was mentioned multiple times. While I found basic definitions online, I found this book mentioned a few times, and thought that it might help teach me exactly what everyone was so hyped up about.

So, "American Exceptionalism" is the concept that America is a special nation, as first mentioned by de Tocqueville after a visit here. The term has transformed, until now, it refers to how America believes that it can justify its actions simply by dint of its "exceptionalism", and ignore the consequences as less exceptional nations cannot.

The book's premise is that America was founded upon principles of life, liberty and pursuit of happiness, and as admirable as this is, our pursuit of them in the modern day has stretched too far in three spheres: political, economic, and militaristic. The book goes through the three areas, giving the history of how we arrived at the current conditions in said area, and how we are pushing the limits of power.

The book, I thought, was very good in that it was very well-researched and made a great many points, but my difficulty with it is that I can't tell its actual purpose. The author lambasts the entirety of the U.S., and so alienates anyone he might be persuading. If the book is just to inform, it's quite interesting, but in that case, why the acerbic tone? As such, I think the book fails to accomplish whatever purpose it was intended for, but it was still a very interesting read. I recommend it to those interested in U.S. politics.

P.S. This guy has a love relationship with Reinhold Niebuhr, a well-known theologian whom I had to read last semester for my religion class.
