No need to be embarrassed or ashamed. You didn't have anything to do with it and you couldn't have prevented that. Many far worse things tha happened there. If one wishes to be embarrassed or ashamed of anything that occurred in or about Viet Nam, one could start with the fact that the Brothers Kennedy started the totally unnecessary war to boost the US economy and to prove the Democratic Party could be tough on Communism. It was a war in which we had no business and in which there was no real US interest.
