A great number of people view the Viet Nam war, as a series of both political complacency and blunders/disasters thereof.And in consequence its opposite bury their own heads in the sand and pretend patriotism.
This proved a turning point for the 1st time in military history.
National service terminated.
From the social perspective, (and generated from the social realisation of the Korean conflict just 10 yrs prior,) a social mass awakened such arousals.
Nation begun to feel the sense/effects of individual loss for the 1st time, and thus discarding the sense of justice. A watershed in the books of history. .
Just my thoughts. Yet such a fascinating period in history.
