Paul Krugman: Europe the Unready

The politics of immigration are nasty everywhere — just listen to Donald Trump or Ted Cruz. But Europe is also trying to maintain open internal borders while leaving the management of external borders to national governments like that of impoverished, austerity-ravaged Greece. The alternative is to take a step back, which is already happening on border controls. European leaders are, rightly, concerned that each such move damages the whole European project. I’m just thankful that America has the kind of unity Europe can only dream of — at least for now. I guess we’ll see what’s left after President Trump gets done with it.
