Saudi Arabia is building great wall — or rather, a great chainlink fence with razor wire — to "protect against ISIS" in Iraq. And it's not the only country investing in very expensive walls right now, even though they probably won't work. Why?Because walls aren't just about security. They're also powerful symbols.,Saudi Arabia wants to "insulate itself from the chaos engulfing its neighbors," and it's doing so with a supremely high-tech wall. Two high fences, 300 feet apart; 40 watch towers; 900 miles of fiber optic cable; underground movement detection. Saudi Arabia's government hasbeen talking about this wall for a loooong time—since 2006—but in early January, ISIS attacked a border postand killed four guards, making it very clear that Saudi Arabia is a big target, and raising the question of the wall once more.
But will a glorified fence really keep out a nebulous group like ISIS? And is that really all this wall is designed to do?
