Query: What a waste!

The book contains so many inaccuracies that I asked myself where the author has been during all these years!The content is self-serving and insults everybody, with one exception, the author himself. It is a shame that 27 years after the collapse of South Vietnam, one of it's leaders has not learned any lesson. The poor people and soldiers of South Vietnam should feel humiliated with such a non-elected leader! And those in the US who have sacrified for a good cause in Vietnam insulted. What a waste! ...Xuan Nguyen
