One of the darkest sides of espionage is covert action. oftentimes an agency or government isn’t content to merely observe and report on international developments; they also want to steer those developments in a manner that benefits them, to the detriment of their target. Because of the covert nature of these activities, many intelligence agencies have developed unique and fiendish weapons that can either kill silently, or be disguised as an innocuous item, or both. This type of covert action has been described differently by those who use it. The Russians call it mokroye delo, or “wet work”. The CIA at one point used the euphemism “terminate with extreme prejudice”. but whatever it’s called, the act of covert assassinations has been used extensively throughout history.
