Obama will also need to pursue negotiations to persuade North Korea to return to the Six-Party talks with the objective of eventually giving up its nuclear weapons (as South Africa once did). And, of course, he will need to pursue the negotiations with Iran to persuade them to keep their word and remain in the NPT as a non-nuclear weapon state.
奥巴马还需要说服朝鲜重回六方会谈并最终放弃其核武器（如从前的南非那样）。当然他也必须与伊朗讨价还价，确保伊朗人能信守承诺，并作为一个无核武器国家继续留在《核不扩散条约》之内。
