The Antarctic Treaty of 1959 was a notable achievement given that the world was in the throes of a Cold War. The treaty set out a framework for the demilitarization of the Antarctic and the promotion of international scientific cooperation. Today the parties involved continue to respect the spirit and content of the treaty. ‘Governing the Antarctic’ considers the last 50 years and reflects on how the Antarctic Treaty Consultative Parties worked to create an evolving international institutional and regime-based structure. However, the potential for future discord and conflict does exist. The sovereignty of the region remains undecided. It seems that the attitude of the United States is going to be key.
