For the novel 1984, George Orwell came up with the concept of Newspeak, closely based on English, but with a greatly reduced and simplified vocabulary and grammar. During the Vietnam War, the American military chose a diametrically opposite path, using convoluted terminology to gloss over the real purpose of war, which is to kill people. Instead of civilian casualties, there was collateral damage; troops were eliminating a target, rather than killing enemies. In the current so-called War on Terror, the in term is coercive interrogation, rather than plain old torture.
Here’s a very disturbing example of another military euphemism, waterboarding. It sounds like something you would enjoy while visiting the beach. It’s not. It’s torture.
