朝鲜最近声称已完成对其核弹头的小型化，美国对这一说法持怀疑态度的同时，越来越担心平壤可能会向其他国家输送核技术或核材料。
分析人士说，虽然对平壤核项目的先进程度存在不同评估，但几乎没有疑问的是，朝鲜正在扩充其核储备。美国约翰斯·霍普金斯大学国际研究所的核问题专家们估计，朝鲜目前拥有10至16枚核弹头，到2020年，朝鲜拥有的核弹头可能会多达100枚。
曾任美国中央情报局长和国防部长的帕内塔说，平壤进行核输出的可能性是切实存在的。
前美国国家情报总监布莱尔警告说，在国际社会加紧制裁朝鲜之际，平壤更可能会出售其核材料或核技术，以换取现金。
While North Korea’s recent claim that it has miniaturized nuclear warheads drew skepticism in the United States, there is growing concern in Washington that Pyongyang could transfer nuclear technology or materials to other countries.
Analysts say there may be mixed assessments of how advanced Pyongyang’s nuclear program is, but there appears to be little doubt that the country is expanding its nuclear stockpile. Nuclear experts at Johns Hopkins University’s School of Advanced International Studies estimate that North Korea currently has between 10 and 16 nuclear weapons and it could possess as many as 100 weapons by 2020.
Leon Panetta, a former CIA director and former U.S. defense secretary, said Pyongyang’s nuclear transfer is a “very real concern.”
Former Director of National Intelligence Dennis Blair warned Pyongyang could be more tempted to sell its nuclear materials or technology to earn cash amid increased sanctions.
