The '''Bureau of International Security and Nonproliferation''' ('''ISN''') is a bureau within the [[United States Department of State]] responsible for managing a broad range of [[nonproliferation]] and [[counterproliferation]] functions. The bureau leads U.S. efforts to prevent the spread of [[weapons of mass destruction]] ([[nuclear weapon|nuclear]], [[chemical weapons|chemical]], and [[biological warfare|biological]] weapons), their [[nuclear weapons delivery|delivery systems]], [[conventional weapons|advanced conventional weapons]], and related materials, technologies, and expertise. 

It was created on September 13, 2005, when the Bureau of Arms Control and the Bureau of Nonproliferation were merged. [[Stephen G. Rademaker]] was the first Acting [[Assistant Secretary of State for International Security and Nonproliferation]]. He had been the Assistant Secretary for the Bureau of Arms Control, and in February 2005 he was named the head of the Bureau for Nonproliferation pending the two bureaus' merger.
