War...What's your view?

Today everyone has a different opinion about war. Some are in favor of it and some detest it. Still some are indifferent. For example people tend to be in favor of World War Two. In contrast, most hold the opinion that the war in Vietnam was a senseless war. People may think this way because we won World War Two, but we lost the war in Vietnam. It seems to me that people think war is fine as long as America wins.
The truth is that war is not fine. No matter who starts the war there are casualties on both sides. In the novel Slaughterhouse-Five, Kurt Vonnegut expresses his opinion on war. Here is a quote from pages 134-135 of the novel. "Billy asked them a little about themselves, learned that the boy's father had been killed in Vietnam--in the famous five-day battle for Hill 875 near Dakto. So it goes." From this passage it is plain to see Vonnegut's point of view. He is opposed to this and every war in general. What he is saying is that the boy's father died in vain. He was fighting for no reason. After all who will remember the battle for Hill 875 when they think of the Vietnam war? Basically the boy's father died in vain.
Also Vonnegut frequently says the phrase "so it goes" when someone dies. Here he tries to point out how people are changed by war. When they have been fighting for so long, they become immune to the pain of war. I mean by this that it no longer becomes hard to kill. After all when people are in war they may kill dozens of people. After that one more person really does not make that much difference. This is what Vonnegut is trying to say about war.
