Do we open up?

If you take any of the big motivating debates in politics today, in Europe or America, international engagement or isolation, immigration -is it good or bad, free trade — a benefit or a fear. Each essentially has, at its core, this question: “Do we open up? Albeit with rules and controls, or do we hunker down, do we close ourselves off and wait till the danger has passed? Is globalisation a threat or an opportunity?” It’s the same central issue.
