Iraq, Vietnam and public perception
LOL. You act like I wasn't around for 1967 - 68. I was. My classmates had older brothers getting drafted, too. My brother-in-law was in Vietnam and my sister was sitting at home with two kids, scared to death.
In 1972, I was in high school and about to be issued a draft card.
In 1967 - 68, I was in middle school and less aware of national events.
Still, it was hard to miss Walter Cronkite with the nightly bodycount and 90% of America watched Walter Cronkite, every night.
So, there are a lot of factors to consider which are not readily evident to those who didn't live through it.
