As a follow up to the previous shocking revelation more No-Dongs are popping up - with chemical weapon capability - and the US has an outdated policy to deal with them.

"North Korea has developed the No-Dong missile, and is developing Taepo-Dong 1 and 2 missiles as potential delivery systems for its WMD. In August 1998, North Korea flight-tested the Taepo-Dong 1 missile, apparently with a small satellite attached. No satellite entered orbit, but the DPRK demonstrated new missile capabilities with this launch. The Taepo-Dong 2 could have a range of more than 4000 kilometers. North Korea also has the ability to deliver chemical weapons with its ballistic missiles. The implications of the DPRK’s missile program reach far beyond the Korean Peninsula and the Asia-Pacific region, however. North Korea continues to place a high priority on the development and sale of ballistic missiles, equipment and related technology, particularly to countries in South Asia and the Middle East. The United States entered a dialogue with Pyongyang in April 1996 to seek a negotiated freeze on North Korean missile technology exports and indigenous missile programs. Although no agreements have yet been reached, these discussions continue."

As you can see chemical weapons could be deployed by the No-Dongs causing widespread destruction.
