Del Olmo's piece was tainted by just a hint of hypocrisy. After his eloquent testimony of patriotism and desire to serve and doing everything legal, like registering even though he was opposed to the war, he kills his point when he says "luck was with me, and I was never called up."
Then there is the anguish over two relatives and a close friend who were killed in Vietnam, but then he refers to Mike Royko's "war wimps" as those who are ready for a fight as long as someone else does the fighting.
It sounds to me like Del Olmo's two relatives and his close friend did the fighting--and dying--for him. Luck was with him, all right.
