The possible use of atomic, biological, chemical or radiological weapons (ABC weapons) constitutes a threat to international security – all the more so because terrorist groups could obtain access to them.
Switzerland seeks the comprehensive, worldwide elimination of all ABC weapons. It has ratified all the international treaties on the subject, and it seeks to make them universally valid and to close any loopholes they may contain. Switzerland also supports international preventive measures (export controls), which are not binding in terms of international law.
