The United States and other Western countries in recent years have taken a tougher approach to a worldwide refugee crisis that has grown to affect 65 million people, the greatest number displaced from their homelands since the wake of World War II.

Australia’s experience is one notable example. President Donald Trump has said that the United States would cap the number of refugees it accepts to 45,000—less than half of those accepted during the last two years of the Obama administration—but is accepting dozens of refugees that Australia has kept in offshore detention centers, a deal cut under President Barack Obama that made headlines at the start of the Trump administration when it was the subject of a famously acrimonious phone call between the new president and Australian Prime Minister Malcolm Turnbull.
