If you know nothing else about a book, it seems a pretty fair bet that one about war is more important than one about beards.

Let me put another way. You need to rebuild civilization from nothing. There's two books left from the pile of rubles and you can only save one before the whole thing collapses. One appears to be about war, the other teaches the best method to maintain the most handsome old school handlebar moustache.

The question is, are you serious about this civilization thing or are you just out of your mind?
