Why Border Walls Fail

Since the end of World War II, the world has built more than 60 border walls, and politicians in many countries – including the US – are busy planning more. And yet existing border walls are neither cheap nor effective.

HONOLULU – Call this the Year of Border Walls. In 2015, Estonia, Hungary, Kenya, Saudi Arabia, and Tunisia all announced or began the construction of barriers on their frontiers. We may live in an era of globalization, but much of the world is increasingly focused on limiting the free movement of people.
