There are some who would urge that we all remain calm (good advice in most circumstances) and somehow take comfort in the fact that North Korea still faces many serious technical hurdles before it can successfully add nuclear weapons to its considerable conventional arsenal. After all, it took the United States 12 years to mount a weapon on a missile.
有人敦促我们无论如何要保持冷静（多数情况下这都是正确的建议），并以朝鲜要想成功在本已庞大的常规武库中加入核武器尚需克服众多难以克服的技术障碍而聊以自慰。毕竟，美国花了12年时间才在导弹上加载了核武器。
