Irony is a literary technique where the intended meaning of words is different from their literal meaning, often highlighting contradictions or unexpected outcomes. Satire, on the other hand, uses humor, exaggeration, and ridicule to criticize and expose the flaws or vices of individuals, societies, or institutions. Both irony and satire are powerful tools in anti-war literature, as they reveal the absurdities and moral contradictions surrounding warfare, often provoking readers to question prevailing narratives and attitudes about war.
