Would the comparison be valid?
Not a chance, and for several reasons. Would you care to venture a guess on say, oh, two easy reasons why the comparison is invalid?
Well, permit me to comment on possible objections to my question.
Pyle was with a front-line American military unit. Foley was not. Foley was on his own. But does that mean no journalist should cover a story unless the American military is involved?
Pyle's America was in a declared war. Foley's America was not. But again, does that mean no journalist should cover a story unless there is a declared war?
Bottom line (unless I see hard evidence to the contrary): Both Pyle and Foley were brave men dedicated to their professions. Both men took risks, and both men lost.
