A crazed gunman's attack on an Orlando club in June, killing 49 people, resulted in blanket news coverage and national trauma.
Now imagine that such a massacre unfolds more than five times a day, seven days a week, unceasingly for five years, totaling perhaps 470,000deaths. That is Syria. Yet even as the Syrian and Russian governments commit war crimes, bombing hospitals and starving civilians, President Obama and the world seem to shrug.
