During the 1970s and 1980s the United States led the world in negotiating one of the most important treaties in history, the United Nations Convention on the Law of the Sea (UNCLOS). Today UNCLOS is in force for 168 countries and the European Union. Isolationist arguments, however, have for a quarter-century prevented the Senate from voting on the Convention. This book discusses the robust reasons favoring the Convention, and offers a sharp critical examination of the arguments still being made against it.
