Vacationed in Vietnam some years back (mostly in the north) and was amazed at the ability of those folks to compartmentalize. They are friendly and kind people but don't poke a stick in their nest -- they'll sting you. But ... I didn't catch a whiff of grudges or resentment, apart from the fact what we call the Vietnam War, they call the American War of Aggression -- and that was just a statement of fact so far as they were concerned.
