把这一句，留给此刻的你

There's a long record here of being wrong. There's a good reason for it. There are probably multiple reasons. Certainly proliferation is a hard thing to track, particularly in countries that deny easy and free access and don't have free and open societies.

有很长一段错误的记录。这是有原因的。原因可能有很多。当然，核扩散是一件很难追踪的事情，尤其是在那些拒绝方便和自由进入、没有自由和开放社会的国家。
