News from Pakistan is often confusing for readers in North America and Europe. Few can keep track of the military, political and religious factions and forces at play. What comes across is usually only a vague understanding that the country is a volatile place in a troubled region. It might matter to the wider world, but that world doesn’t often make the effort to grasp even the broadest outline of the problems. But this morning’s news doesn’t require that sort of effort to comprehend: in Pakistan’s worst aviation accident ever, a passenger jet crashes outside Islamabad on Wednesday, killing all 152 people aboard. It’s a terrible story that might remind jaded readers that even in the most maddening complex country, there’s an awful simplicity and similarity at the core of every human tragedy.
