Proliferation on the peninsula :  five north korean nuclear crises 

 - Thousand Oaks :  SAGE,  September 2006 
<br/><br/> To reduce the risk of nuclear terrorism, we must prevent terrorists from obtaining nuclear weapons or materials. This will require, among other things, a sustained effort to keep dangerous nations from going nuclear—in particular North Korea. This article reviews the efforts the United States has undertaken through the years to keep North Korea from building a nuclear arsenal, arguing that the history of proliferation on the Korean Peninsula is marked by five nuclear crises. A sixth could be on the horizon, further compromising American efforts to lessen the likelihood of a nuclear attack on U.S. soil.
