Summary: a further compelling lesson on geopolitics from Tim Marshall who highlights some of the challenges – and opportunities – that humanity will face in the coming decades
The Power of Geography is a follow up to Marshall’s magisterial introduction to geopolitics, Prisoners of Geography.

In this volume he focuses on some emerging issues, including how we as human beings will explore space. He also discerns potential for conflict arising in important parts of the world, such as the Sahel and Ethiopia. These places are often little understood to outsiders. But issues arising there are likely to have a huge bearing on the course of human events in the coming years as ancient national aspirations, global warming and competition for water forces political choices that will ripple out across the planet.
I regretted that Prisoners of Geography had no discussion of Britain and Ireland. This book does have a discussion of the UK, currently a leading contender for the title of most bizarrely deluded country in the world.
It has earned this unenviable accolade by deciding to make policy for itself with almost no discernible consideration of geography. Brexit, the fevered wet dream of a few disaster capitalists and frothing xenophobes, has now become the guiding principle of UK policy. Marshall pays little attention to the disastrous impact of this policy on Irish peace, which was built on the foundations of the UK’s and Ireland’s common European Union membership. But he does note how it has added impetus to the Scottish desire for independence. This consequence of Brexit would, Marshall observes, likely cause greater damage to the UK’s international standing than Brexit itself.
If that happens it would be a deserved fate. Over the past half decade the UK seems to have embraced a vision in which international rule of law should not apply to it. Hence its legal commitments are today hardly worth the paper they are written on. Such rogue states are not deserving of respect.
Of course, Marshall has a much broader perspective in this book than the repercussions of Brexit. His discussions also encompass Iran, Saudi Arabia, Turkey, Spain, Greece and even Australia. Each chapter is filled with fascinating historical and geographic detail and a clear perspective on their geopolitical implications. It is an outstanding companion to Prisoners of Geography and an essential book for anyone interested in current affairs and the issues that may confront us in the coming years.
