The North Atlantic Treaty Organization, or NATO, is a multi-government military alliance between 29 North American and European countries. It began with 12 countries, and it will soon turn 70 years old. What is the future of NATO? (Especially at a time when the U.S. President has openly and publicly questioned the very importance of NATO....) What are NATO's main aims or goals -- and how have these changed over the years? Our guest on ST is Steven Hill, who was appointed the Legal Adviser and Director of the Office of Legal Affairs at NATO Headquarters in Brussels in February of 2014. In this role, Hill is NATO Secretary General Jens Stoltenberg's chief legal adviser. Hill recently gave an address at the Tulsa Committee on Foreign Relations titled "NATO at 70: The Current and Future Missions for the Alliance."
