核警察

  洛杉矶-四十年前的本月,50多个国家聚集在白宫东厅签署了《不扩散核武器条约》。在其论文集中,美国总统林德·B·约翰逊把该条约称作“至今为止我们采取的降低核战争可能性的最重要的措施”。

现在,随着时间的推移,我们可以评估这个条约是否真地标志着约翰逊总统所希望的“历史性的转折点”。证据显示,虽然该条约的堤防大部分被守住了,但是,也产生了严重的漏洞,促使核警察在当他们断定外交不能停止核扩散的时候使用武力。这种行为是否是未来行为的先驱尚不清楚,但是,鉴于《不扩散核武器条约》没有包含一个有效的执行机制,它增强了持续萦绕在人们心头的担忧。

有一个事实是毫无疑问的:除了三个国家——印度、巴基斯坦和以色列——以及一个退出的国家,北朝鲜之外,《不扩散核武器条约》是签署并核准它的国家的核不扩散制度的法律支柱。该条约的原则仍然很坚决:条约公认的五个拥有核武器的国家——美国、英国、法国、俄罗斯和中国——承诺清除他们的核设施,其他缔约国承诺不取得核武器,并以此交换在遵守有约束力的安全保障制度的情况下,在国际力量的支持下发展民用核能的权利。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
