What is the theme in Goldfinger by Ian Fleming?

Cold War Tension would be a theme in this story.

Following World War II, the United States and the Soviet Union, who had been allies during the war, emerged as the two major world superpowers. The two nations eventually became enemies over the conflicting ideologies of Communism and Capitalism and began a decade's long conflict known as the Cold War, because it never erupted into open fighting between the two countries. Instead, the war was fought by proxy in places like Korea and Viet Nam, and also covertly as spies from both sides tried to discover each other's secrets.
