Question: how did things change after the Vietnam war? 

Answer: Well over the long term- people's attitude toward the military.  During the Viet Nam era, military people were treated very badly (and this is really an understatement). Now people in the military are given the recognition they deserve- these are people who have volunteered to help their country. \n\nAlso, this country no longer has a draft and depends on an all volunteer military.
