chemical weapons convention

During and after the Cold War many effective arms control agreements with regard to Weapons of Mass Destruction were successfully negotiated. Yet, in the last few years many of these agreements have been abandoned or are under pressure. What is happening?

My hope is that governments, and in particular the so-called domestic ministries, will open their eyes and recognize that the future of their countries not only depends on how they deal domestically with education, public health, environment, science, crime, etc., but at least as much on how other countries deal with these issues. If they recognize that, the importance of strengthening the UN system will be self-evident.
