The question has already been answered so here is a semi-related anecdote.

I watched The Grand Tour episode where they took boats from Cambodia to Vietnam not too long ago. It's an extremely deranged bit of television. Along the way, Clarkson stops to talk sincerely about "history". He bounces between teary-eyed valorisation of Americans during the war and passionate condemnations of Pol Pot. The juxtaposition implies the Americans were against Pol Pot and that the Vietnamese supported him, completely the opposite of reality.
