"Dark War: Secret War Files of Great Powers Declassified" is launched after "Insidious: Declassified Files of International Spies Masters". This book is different from "Insidious: Declassified Files of International Spies Masters" which tells a single spy story. Instead, it focuses on telling the conflicts, struggles and even wars of the United States, the Soviet Union, Nazi Germany, Britain, France, Israel and other major powers. The historical background is World War II or the Cold War, and espionage activities were interspersed with wars. These espionage activities show wonderful stories, such as the struggle between eavesdropping and counter-eavesdropping between the United States and the Soviet Union, the United States' operation to steal the "secret report" of the 20th Congress of the Soviet Communist Party, the dangerous operation to steal the "Phantom" fighter blueprints, the "Heavy Water Operation" that shattered Hitler's atomic bomb dream, the "Mincemeat Project" known as the largest espionage scam in World War II, the "Guardian Project" that used lies to protect the Normandy landing, and so on. Each story has twists and turns, intertwined events, and complicated relationships. Politicians from various countries are involved, fighting overtly and secretly, and using their best efforts. This book is more readable. Each exciting, thrilling, witty and martial story will give readers a new understanding of the war and even the world situation at that time. It can be said that these espionage activities rewrote the history of the world and changed the world situation at that time, and also had a profound impact on future generations. Whether it looks good or not, you will know when you open this book...
