EDIT:
Sorry the heading should be changed to 1973. For those looking for more detail to the question: I was curious how a country that was in civil war and was fighting with the US for so many years eventually stabilized and is today a pretty peaceful country.
This is a very broad question you're asking. First of all, the US military left South Vietnam in 1973. What exactly is it that you're curious about? Social? Political? Military? Directly after the fall of Saigon or up until the present day?
Thanks a lot guys for all the responses some great reads.
