Maybe a Motif?

Okay so this may be a stretch, but I am going to go for it. Even though I have only tackled the first 56 pages of the book, I think I may have found a motif. On page 38, O’Brien mentions the novel (novel during this era atleast) concept of America “not fighting a war unless knowing why". Hmm does this not resemble what is currently happening in the second Gulf War? (tell me what y’all think!) I could be wrong at this point in the novel, but my intuition tells me this notion will keep appearing in the book. I also think that as of right now, this could develop into the common theme of the story- one of questioning and uncertainty.
