The major topics discussed in Lessons to be Learned from Non-Proliferation Failures and Successes are divided into thematic parts and cover a wide range of issues, both from functional and from regional points of view. The first part of the book extends from assessing 'sticks' and 'carrots' in the non-proliferation arsenal of the world community, to drawing a more precise line between non-proliferation and counter-proliferation measures, and further to comparing UN-based and national level sanctions and efforts aimed at reassuring non-proliferation. Special sections are devoted to Nuclear Weapon-Free Zones and 'negative assurances' in their relations with non-proliferation, as well as to risks of Weapons of Mass Destruction (WMD) terrorism and of further proliferation because of abundance of not so well-managed fissile materials in the hands of nuclear powers. The second part of the book deals with the lessons learned (or that need to be learned) from the concrete regional cases of proliferation or its risks.
