I came across a segment of a poem a few years ago while reading the book "With The Old Breed" (a really good book by the way) that this reminds me of. It's one of those things thats always stayed with me.
This is for those who would vote for and support war but would never think twice about participating in it.

"You smug-faced crowds with kindling eye
Who cheer when soldier lads march by,
Sneak home and pray you'll never know
The hell where youth and laughter go."
From "Suicide in the Trenches" by Siegfried Sassoon.

People need to understand what war is.

Many generals considered those who suffered shell shock to be cowards, and a large number were executed. They were not executed for having shell-shock, they were executed for specific military wartime offenses, such as desertion under fire. The British Army apparently executed a significant number of soldiers for such offenses.

He didn't limit himself to that, he cussed out injured soldiers who said they were scared to go back to the front.
