Interest in international law has increased greatly over the past decade, largely because of its key role in such hot-button issues such as the Iraq War and Guantanamo, the World Trade Organization and the anti-capitalist movement, the Kyoto Convention on climate change, the apparent failure of the international system to deal with dire situations in Palestine and Darfur, and the plight of refugees and illegal immigrants around the world.This Very Short Introduction explains what international law is, what its role in international society is, and how it operates. Dispelling many of the myths surrounding the topic, Vaughan Lowe clearly outlines what international law can and cannot do and what it is and what it isn't doing to make the world a better place. Lowe focuses on the problems the world faces, using terrorism, environmental change, poverty, and international violence to demonstrate the theory and practice of international law, and showing how these principles can be used for international co-operation.ABOUT THE SERIES:The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.
