Just Finished Reading: Divided – Why We’re Living in an Age of Walls by Tim Marshall (FP: 2018) [288pp] 

Walls, be they metaphorical, electronic or physical, seem to be THE topic presently. From the ‘Great Firewall of China’ to the ‘southern Border’ in the US, from the wall separating Israel from the Palestinians to the barriers between India and Pakistan, from the walls being erected on the borders of the European Union and calls for stricter interior controls and the rejection of the free movement of people by the UK in the Brexit vote, talk of walls – the need for more, bigger, wider, deeper – and protests against them has rarely been louder. But why? And why now? 

Walls have a LONG and chequered history. Normally they are built to keep people out, to restrict access to an area or country, to control who comes in. Sometimes they are the opposite – the Berlin Wall being the poster child for this sort of thing – and are designed to keep a population IN. All have failed to one degree or another – although the Berlin Wall was amongst the most successful certainly in modern times. Despite the catalogue of failure, the wall builders rarely give up and instead look for better walls full of gadgets, drones, cameras, and if you’re really serious of keeping people out, men with guns, mines and dogs trained to kill. Yet, people still come, people still get through – or escape. The problem with walls is that there’s often a wall around or through them – be it a ladder, a tunnel, a balloon or simply a bribe at the gate. Most rational wall builders know this. Walls will slow the movement of people, not stop it. Walls are an additional cost – monetary, psychological, emotional – to people looking to relocate. Often the additional cost is worth paying and the cost to be builders to prevent this can be eye-wateringly large. Is it even worth it? 

The issue here, as the author points out, is less practical than emotional. Walls might not make us safe, but they make us feel safer. Or at least that’s the idea. But living inside a wall also makes people feel besieged and under (at least potential) attack. They may feel (at least temporarily) safer but at the cost of increased anxiety. In many ways its completely understandable. We seem to be living in a particularly uncertain time. Ironically, it might have been the falling of one wall – in Berlin – that eventually led to so many of us either cowering behind our new walls or calling for them to be built. The Cold War – however potentially existential it was – provided at least the illusion of stability. Generally speaking, people knew what to expect from their own side and that of the ‘other’. The future, bleak though it might be, was a known quantity. Today we live in a much more complex multi-polar world where the future can be barely imagined (bleak though it is expected to be) much less planned for. The entirely natural instinct is to burrow in, hunker down and protect what you have – in other words, to start building walls or build existing walls all the higher. 

Taking a world tour of wall building – both existing and planned – the author shows (to a surprising extent I thought) the extent to wall building in regional hotspots and along contended and contentious border areas. Most of these walls I’d barely heard of as most talk, at least in the western media is about America’s southern border with Mexico. That is, sadly, not the only one, not the biggest or most expensive or most complex one. With global migration increasing due to conflict, climate pressure and other factors the numbers of people pressing up against walls across the world can only increase. The question for everyone, not just our politicians, is what we can, should, and will do about it. Bigger walls or a more managed and rational process. One way or another we’re going to find out. Definitely recommended, although it might depress you more than a little bit. Much more to come from this author.
