In the seventies, when the cold war was at its peak, Donald Rumsfeld was convinced that the Atlantic Ocean, off the U.S. coast, was teaming with Russian submarines. The U.S. navy couldn’t detect them because, he was convinced, the Soviets had a new ‘acoustic technology’ which made them effectively invisible. Rumsfeld went ahead and ploughed billions of dollars into developing a new technology which could detect the non-acoustic subs. But that failed and is still costing the U.S. taxpayer today. The truth was in fact, the Soviet subs just weren’t there.
