It takes a lot to uproot oneself (and family), arrange travel via a trafficker, step onto a boat with a few possessions and no guarantees.They are called migrants or refugees—or both. Whichever term comes to mind, they are all people, many looking to improve their lot in life. But most, experts say, are running from instability and violence. According to the United Nations, the recent wave of migrants represents the largest dislocation of people since the Second World War. The estimated number of migrants in Europe runs in the hundreds of thousands, up to over a million registered asylum seekers. Thus, the term “migrant crisis,” which is useful shorthand, but doesn’t allow for the scale and scope of human suffering involved. As Europe struggles to cope with the influx (via the sea from Turkey or Libya into Greece or Italy, for the most part), America is bracing for the expected spillover.
