Arguably the greatest spy for the West during the Cold War, Dimitri Polyakov was a Soviet Major General in the GRU who revealed Soviet secrets to the FBI and CIA for nearly 25 years. Polyakov provided intelligence on China and Soviet-era weapons capability and was credited with keeping the Cold War from getting hot.

Vladimir Vetrov was a KGB Line X (technical espionage) officer who worked for the French intelligence service. The Soviet technical and economic espionage material he provided to the French was called the “Farewell Dossier,” and was shared by French President Mitterand with U.S. President Ronald Reagan. He was ultimately betrayed by his own wrong-doing.

Working as an interpreter at the U.S. embassy in Bonn, Gabrielle Kleim was recruited by an East German Intelligence officer posing as a love interest. She was among several West German secretaries recruited by East German so-called “Romeo Spies” working at the behest of the “Man Without a Face,” East German HVA Intel Chief Marcus Wolf.

While a prisoner in North Korea, George Blake was recruited by the Soviets to spy on the British. Blake caused tremendous damage to MI6 and its allies around the world and was ultimately convicted and sentenced to 42 years in prison. He would later escape in an audacious prison break and find refuge in the Soviet Union.

Apple Inc. and Tesla’s autonomous vehicle programs are two of the many high profile companies being targeted by Chinese trade theft. Xialong Zhang, an engineer, with access to Apple’s project code and Cao Guangzhi, an electrical engineer with Tesla are both caught trying to steal secrets on autonomous driving vehicles for a Chinese competitor..

This program uncovers new information about secret spy plane missions flown over communist territories during the Cold War. Over 10,000 missions were flown; many were tracked and attacked by the U.S.S.R., Red China, and North Korea.

During the Cold War, much of the Soviet Union's economy went into developing weapons. With paranoia about U.S. technical superiority at a height, even the craziest sounding idea stood a chance--the military-industrial complex incubated ambitious.

Nuclear weapons didn't die with the Cold War and there's chilling evidence that a nuclear threat could endanger Americans more than ever--a diagram for a nuclear device at an al-Qaida safehouse in Kabul, cases of theft and sales of nuclear weapons material, nuclear scientists for sale, and nuclear materials poorly secured at dozens of Russian sites. Terrorist groups and rogue nations are intent on getting the bomb and, as we see, it may be more feasible than ever for them to succeed.
