I have this image in my mind of him having flashbacks to My Lai and Abu Ghreib type events over and over again.
I can see a t-shirt design...
On the left, under a picture of the fallen soldier's memorial (helmet, gun, boots).
"War sucks!"
On the right, a collage of terrorist attacks on innocent people, Saddam's soldiers marching in formation with missiles, Iran's president with a mushroom cloud in the background, and the world trade center towers being attacked... and underneath, "This sucks more!"
Nobody is truly pro-war, but many of us are against the enemies of our country running free and rampant over others, to build up their arsenals and terror cells so that they can attack us later.
