„… after the war, he became a big proponent of the argument that chemical warfare or gas warfare was actually a more humane form of warfare than shrapnel and bombs, because he saw what all those shrapnel and bombs did to all the boys who climbed out of the trenches and tried to cross no man's land, with German machine guns and artillery on the other side, he said I'll take the gas any day. I'm not making the case for gas warfare, but the idea that getting killed by gas is, more horrible than getting ripped apart by shrapnel and bullets is not one I buy. And when I see the Obama administration putting pictures of people killed by gas up on the internet, I say "let's put pictures of the people who got killed by shrapnel up there, and lets have a debate about which pictures look worse."“

It won't even be an interesting debate, getting killed by shrapnel, in my opinion is a lot more gruesome and a lot worse.
