As Butler tells, he began to see war as a racket while still in uniform. I am yet again riveted every time I read this:
My maternal grandfather was mustard gassed in France in the Great War. He did live to the age of 63, but developed cancer in his 50's. A second cousin on my father's side saw a John Wayne war movie, and joined up for WW2 before he could be drafted. First beach landing overseas he saw some of his buddies blown to bits. I once offered to give him some books on WWII. He replied: "I don't want to see ANYTHING about the war... I was there."
