Thompson's book is a brilliant review not only of American foreign policy since the late 19th century, but more significantly, of the motivation for that policy. Why has the United States acted as it has in world affairs while evolving from a strong regional power to the world's dominant power? In elegant prose Thompson provides persuasive answers and very effectively skewers many prevailing theories.
A sense of Power is a very readable, and sometimes, gripping, history of American foreign policy. For a general reader, like myself, it helps explain the evolution of thought that gave rise to the assumption of the global role America now plays, and illuminates it what happened, why and when during the time between the late 1800's and the Korean War. And many parts of it seem particularly relevant, given today's political debates. I found it a great read and would recommend it highly.
