There is a new survey of Vietnamese history that has just been published. It is a book by Yale professor Ben Kiernan called Việt Nam: A History from Earliest Times to the Present (Oxford, 2017). Kiernan does not know Vietnamese or classical Chinese, but he has read a lot of what has been written about Vietnamese history in English, and he has taught about Vietnamese history for many years.
His book therefore can be seen as an effort by an educated person to try to make sense of the extant English-language scholarship on Vietnamese history. His conclusions, I would argue, can in turn enable people who specialize on Vietnamese history to gain a sense of how well they have been able to educate readers about the Vietnamese past.
