I once read a theory that just before a major war or conflict breaks out, several cultural things are pointing to it. Crap and ugly "art" like this, essays and op-eds everywhere talking about hopelessness or graft, and I also once read somewhere that a couple of years BEFORE a major war breaks out, the number of male births tend to increase compared to girl births. I don't know what the current demographics are about child births in America, but I wouldn't be surprised if boys have been occurring more for the past few years.
