Two Oxymorons on the same page? No way!

I am now going to unravel two phrases found on page 77. "But in truth, war is also beauty." And, "Almost everything is true. Almost nothing is true." Okay as for the first phrase. I am trying to imagine how war can be beauteous, but then I remembered I have never been in a war like the men in the book. I believe that when one is stuck in such of a "Hell on Earth," that in order to stay somewhat sane, one MUST see the beauty in the things others would find horrific. O'Brien mentions some of these things in the lines following the oxymoron. As for the second phrase. When one is engaged in a war, suddenly every movement, every breathe becomes about life, but it also becomes about death (avoiding it). By using such contradictory terms, I think O'Brien is able to convey to the reader the vulnerability of war itself
