King Abdullah had warned in January 2016 that Jordanians have reached “a boiling point”, and called on donor countries to provide more to Jordan to help it cope with the crises. He told the BBC in an interview that "in the psyche of the Jordanian people I think it's gotten to a boiling point, sooner or later the dam is going to burst." Jordan has historically welcomed refugees—Palestinians in 1948 and 1967, Iraqis during the American invasion and now Syrians, who make up about 20 percent of Jordan's then 9.5 million population—and, according to Abdullah, "For the first time, we can't do it any more." The UNHCR places Jordan as the world's second largest host of refugees per capita.
