Why does Peewee seem like a fool with his attitude about this war?

Peewee's attitude about the war reflects a naive and overly simplistic view, as he seems to focus on the excitement and camaraderie rather than the harsh realities of combat. This can make him appear foolish, as he underestimates the seriousness of the situation and the consequences of violence. His enthusiasm may stem from a desire to fit in or escape his previous life, but it ultimately highlights his immaturity and lack of understanding of the complexities of war.
