Operation Paperclip: The Secret Intelligence Program that Brought Nazi Scientists to America by Annie Jacobsen reveals the covert US military operation that recruited over 1,600 German scientists, engineers, and doctors—many former Nazis tied to war crimes—to work for the US after WWII. It highlights the ethical conflict between national security and moral accountability during the Cold War. The book uses declassified documents and interviews to expose how the US prioritizes technical superiority over moral considerations, resulting in a complex, often disturbing,, part of American history.
