How did the American Society cope with Foreign and Domestic Policy from WW2 Until the End of the Cold War?

How did the "American Paradox" manifest itself in foreign policy and American Society until the end of the Cold War?

The American Paradox being after World War 2, the U.S emerges as the sole world power.. While trying to maintain that role, socially and politically in foreign policy and on home soil... How did it manifest itself?

Looking for what I should include, how to structure it, what can I leave out, what must be included... how would you describe the paradox..

We are using a book called the "American Paradox" a History of the US since 1945 by  Steven Gillon. I am not doing a book report or an analysis on this book, rather this is the book we used during the duration of the course...
