But North Korea’s test this month was by all measures the real thing. Moreover, though it is hard to evaluate North Korean bluster on these occasions, there appears to be reason to be concerned that North Korean scientists have also made progress in miniaturizing their design, a step needed to mount a nuclear device on a missile.
但无论从何种角度，朝鲜本月举行的核试都再无值得怀疑之处。此外，尽管很难估量朝鲜在上述核试中有多少恫吓成份，但似乎有理由担心朝鲜科学家在实现设计小型化（在导弹上安装核装置的必要步骤）方面也取得了进步。
