Book Review: "Gun Country: Gun Capitalism, Culture, and Control in Cold War America"

Author Andrew McKevitt's book Gun Country posits that America's unique love for guns appeared in the late 20th century, growing out of a love of cheap WWII surplus arms, Cold War commie fear, and 1960s race riots. Is it this simple? And is his description of "gun capitalism" a helpful way to talk about the Citizen Defense Industry?
