The CBRN threat: Past, present and future

Abstract

In recent years world leaders, news media and experts have warned of the global security threat from chemical, biological, radiological and nuclear (CBRN) material and weapons. Last December, a bipartisan U.S. commission cautioned that “unless the world community acts decisively and with great urgency, it is more likely than not that a weapon of mass destruction will be used in a terrorist attack somewhere in the world by the end of 2013.” In parallel with the 20th anniversary of the fall of the Berlin Wall, it is interesting to highlight the Cold War origins of many modern-day CBRN challenges. At the same time, this article explores how newer developments have been infusing additional complexity into the global CBRN threat landscape.
