EU leaders reach migration deal

Migration has "been one of the biggest crises that the European Union has faced in a decade where there have been several crises in a row," John Springford, deputy director of the Centre for European Reform, told CBS News.
..."For a lot of people on the right, this is a hugely problematic issue," Springford said.

...Springford said the number of asylum seekers who have arrived over the last several years -- between 1.5 and 2 million -- should be relatively "easy to absorb" given the European Union population of about 500 million.

"But if we think about it on a political level, it's much more difficult, because a lot of populist politicians have been using the migration issue and using popular frustration about the number of migrants who are coming across, and demanding change, and making it the number-one issue facing society," he said.
