Mankind must put an end to war, or war will put an end to mankind.—John F. Kennedy, Jr
For this example, John F. Kennedy, Jr simplifies his large political idea into a short and simple statement. Using a short and simple statement to persuade his audience is clever because it leaves no room for doubt. In addition, Kennedy employs a trope as the format of his statement. Since this statement effectively uses clear chiasmus structure, the audience can easily understand and remember Kennedy's statement. The clever chiasmus format and clear message in this statement distinguishes it as a epigram.
