The point you are missing, is that these guys were told that they were sent over to the desert to accomplish a mission and do good. The military brainwashes these men into becoming ruthless, heartless animals. They are training in 110-120 degree whether, for an enemy that they are supposed to be stopping, but when time comes to fight this enemy, nothing happens. They spend a year away from their friends and family. While time slowly passes though the desert heat, back home the world continues as normal.
So they accoplished nothing at all. Then everything that they wanted to return home to see, wasn't there.
Swoffard went in there being skeptical of the whole military idea, and didn't even want to join, but he had no choice. Time over there changed him completely. And to top it off, the girl that he loved left him for another guy while he was away. Which probably wouldn't have happened in his mind if he wouldn't have been over there. That girl was the only real thing he had left to come home too. His mother was crazy, father gone, sister in a mental hospital.
I completely agree with you that these men don't go through what soldiers of ,lets use the example of WWII, go though. But in something like WWII, the entire nation was involved in the war effort. So every girl's husband or boyfriend was over seas. And everyone's daily life revolved around the war. And everyone had to contribute. Something like this is totally different. A select few men are sent over there (most who don't want to be), and everyone back home doesn't even notice let alone care.
If you have read any of the anti Iraq posts on here, you'll know that I am one of the most outspoken contributors. But I have not let those views get in the way of how I feel about these soldiers.
