My brother and I enlisted in the US Army in 1968 around the time of the Tet Offensive.
We were just two young, starry-eyed, dumb kids trying to help the country and find a way to get to college at the same time. Our Mom and Dad supported us. My brother went to Vietnam, I did not, due to an injury.
When my brother came home, he was so skinny from being sick with Malaria that we hardly recognised him. He had some medals and a stomach ulcer. 20 years old.
Would I volunteer today, for Vietnam?
No way, unless it was to be with my brother.
