Doonesbury by Garry Trudeau for March 08, 1972
George: Hear about the bombing raid last night?...2,300 tons! B.D.: That wasn't a bombing raid! It was a protective reaction strike! George: B.D., they drop bombs in both cases. There's no difference. B.D.: There's a big difference, fellah! A protective reaction strike means not having to say you're sorry.
