I didn’t say it wasn’t
Look at the average age of Viet Nam Vets vs the average age of WWIi vets. No one was lining up to go to VN like they were for WWIi
It was 22 in Vietnam and 26 in WWII, but 18 year olds were drafted in WWII and forward to 1973.
WWII was a mostly draftee war as was the Korean War while Vietnam was fought by mostly volunteers.
I enlisted in the Corps at 17, had to get MOM to sign off on it.
