Say one thing, mean three: the strategic use of contradiction in Propaganda during the second Indo-China (Vietnam) War

What if propaganda doesn’t resolve contradictions, but amplifies them on purpose? This study explores how Vietnamese communist strategists weaponized contradiction not as a failure of logic, but as a deliberate tool of psychological warfare. Through a mixed-method content analysis of 102 propaganda documents, we examine how contradictions, explicit, implicit, antagonistic, and layered, were deployed to polarize identities, manage ideological complexity, and erode enemy legitimacy. Although contradiction framing was present in only a subset of texts, it consistently aligned with specific persuasive functions, including appeals to authority, moral reasoning, and U.S. value targeting. These findings challenge Western assumptions that view contradiction as a communicative flaw, revealing instead its strategic utility in high-context revolutionary messaging. In showing how contradiction can both clarify and destabilize, the study offers fresh insight into the rhetorical mechanics of communist propaganda – and valuable tools for decoding the language of information warfare.
