in what way does genes view of the enemy differ from the view of brinkers dad?

Gene is introduced to Brinker's dad, and says that he has joined the Navy. Brinker has joined the Coast Guard, probably part of his scheme to stay out of battle. Brinker's dad is very gung-ho about the military, and gives the boys a speech about having a good military record, and how people will respect them based on what they did for the war. Gene doesn't think the war is as honourable as Brinkers's dad claims.
