I have seen references to a &quot;stab in the back&quot; myth&#x2F;belief for Vietnam e.g.<p><a href="https:&#x2F;&#x2F;newrepublic.com&#x2F;article&#x2F;64982&#x2F;the-other-vietnam-syndrome" rel="nofollow">https:&#x2F;&#x2F;newrepublic.com&#x2F;article&#x2F;64982&#x2F;the-other-vietnam-synd...</a><p>[NB I&#x27;m not in the US so I have no idea how popular these beliefs are - I suspect they aren&#x27;t <i>that</i> common and perhaps quite understandable given the impact Vietnam had on the US].
