Complaining = Change?

Swafford ended by saying, "some wars are unavoidable and need well be fought, but this doesn't erase warfare's waste. Sorry, we must say to the mothers whose sons will die horribly. This will never end. Sorry." At one point Swafford had me completely confused, but at the end of the memoir, he makes it clear about why he wrote it. He felt the need to complain about his experiences in the marines and what the marines stands for. Swafford wasn't the only marine that complained, they all complained http://www.youtube.com/watch?v=DCyzLHQ_fro, but Swafford continued to do so even after the war was over.

Maybe by him complaining things might change. He doesn't expect the wars to end, but he does hope complaining would change the experience of a marine. In "The Things They Carried," O'Brien had a different perspective about his experience. He prefers to metaphorically tell war stories. In fact he and many are actually sad and this is there way of complaining.

Is Swafford complaining because he had a bad experience? I think he's complaining because he didn't have any excitement. The ones that were spared, as himself, don't understand the reason that many died and they didn't.

In every war occurrence there is a complaint. In the movie, "Home Of The Brave" the characters are having a hard time adjusting to their lives. There is a change in activities, change in sleep, change in their lives. The families are having a hard time with the change as well. They complain about the way their loved ones return to them. Is the complaining going to cause change for the better or the worse? Is Swafford's complaining going to cause change, change in the structure of the what?
