There were more than 2 million draftees.
Not everyone in uniform was enthusiastic. I would love to believe that was the case. The draftees did their duty, so it isn’t a slam. But the truth is different than the John Wayne movies.
That’s beside the point. The point is that 16 million served.
The unenthusiastic you mention were a very small number.
As a VN combat vet I know all about “the truth is different than the John Wayne movies”.
