War, Huh, Good God Ya'll

I have decided to modify my views on the former student who came into our class. My primary reaction to his account on experiences overseas was admittedly extremely defensive. His frank attitude about such a controversial area of issues stunned me. But after discussing my feelings in class, I realize that I gave no credit to his experiences and, it must be said, his bravery. Though he explained that he went into the service without much direction, I must commend the poise he now has and the pride he clearly has developed in what he does. Now, I will say I have not completely changed my concerns about his attitude, but simply have forced myself to appreciate his situation. Certain dealings he spoke of still disturb me greatly, and many of his descriptions chilled me, but I realize now that being personally offended by his actions is completely useless. I have zero understanding of his operations in Iraq (was it Iraq?) and only reacted to his statements based on my own morals. Morals, it seems, must be adjusted for such things. That is why now, the only thing that truly disturbs me, is the minimal help the troops get upon returning to America. I imagine that the army forces troops to endure such vigorous training in order to rid the trainees of any need to think independently of the tasks assigned to them. I do not mean that in a negative way, just that they are trained to do things a certain way, and if it is not done in this way, there is a negative consequence. This simplifies everyday actions to the point where everything is routine. If this attitude can be formed and taken overseas, then you've got a bunch of troops waiting for orders, willing to take them and perform them to their maximum capability in order to not receive said negative consequences. Perhaps I am taking this a little too far, but that what I imagine to be true. In any case, original morals are placed on the back burner and are overcome by personal desire to perform well.
