The book "Who Are We?: The Challenges to America's National Identity" was written by Samuel P. Huntington. In the book, Huntington discusses the influence that other civilizations have had on the identity and the values of people in the United States.
In the book, Huntington disputes the notion that the United States is a nation of immigrants; instead, he states that the United States is a country founded by British settlers, adding that it would have been a different country had it been colonized by a different European nation or at a different time. He also sets forth the belief that American identity began to erode in the 1960s and lays out the challenges ahead for the United States to reassert its core values.
