Actually the cultures of north, central, and south Vietnam are quite different. The accents vary so much that people from one section of the country struggle to understand people from another. They have been ruled by different rulers for much of the last thousand years.<p>Speak to many southern Vietnamese even today and they&#x27;ll tell you the war was an illegitimate land grab of the more fertile and valuable land in the south by communists in the north wrapping themselves in nationalist ideology.
