Reading the comments below, I come to understand that many are missing the point of the essay, or speech as it was intended originally.
For modern readers, Butler's words are not to be taken directly but in context. Butler's point is that war is a racket. That is it. Funny right. If you are to ignore all the details about the casualties and who said what and who did what, you are still left with the essence of the speech. War is a racket. Repeat after me :) If you instill the mindset that war is a racket then all the pieces fall into place. It becomes very clear that war has no regard for human life. That it is detached from reality of life and death.
"Eliot A. Cohen, an official in the George W. Bush administration who is now a professor of strategic studies at Johns Hopkins University, said that Mr. Obama’s trips to Walter Reed may have been the reason, and that future presidents should avoid such visits.
“A president has to be psychologically prepared to send people into harm’s way and to get a good night’s sleep,” Mr. Cohen said. “And anything they do that might cripple them that way means they’re not doing their job.”" -- http://www.nytimes.com/2016/11/29/us/politics/obama-walter-r...
"they’re not doing their job" --- their job being what?
Be smart, war is a racket, and suggesting a president should not be worried about the lives of the people he harms is fucked up. Additionally, presidents should visit hospitals in Syria maybe. Maybe then they will not make the same actions.
