This book examines both the theory of global government and the prospects for it. In terms of the theory, the author contends that modern problems are so big that they can only be dealt with by a global response. Specifically, human rights, climate change and global poverty are named as three of the most important examples. The author feels that these problems require global government.
Concerning the prospects for global government, the author is somewhat philosophical about the chances. He concedes that it seems a long way off. Perhaps most interestingly, he is strongly opposed to regional blocks like the European Union (EU), African Union etc. He argues that far from being regional "building blocks" on the road to eventual global government, they will become self interested power blocs in the meantime, and thus not want to give up their power to a global authority at a later date.
This book is a must read for anyone interested in globalisation, supranationalism or international organisations like UN, EU. Strongly recommended.
