Another textbook just received, also in its new second edition, is Colin Flint, Introduction to Geopolitics. Looks good, and also useful for teaching. Chapter Five is on ‘Territorial Geopolitics’. I do admire people who can write textbooks – not something I think I would be very good at doing. The only textbook piece (as opposed to companions, encyclopedia or dictionary entries, etc.) I’ve written was for the Jenny Edkins and Maja Zehfuss (eds.) Global Politics book – a second edition is in progress – and I found that quite a hard thing to do. That book has an interesting idea behind it, in that each chapter is an answer to a question. Mine was ‘Why is the world divided territorially?’ It’s quite a different challenge to just writing a chapter on territory.
