消失的天空

几个月前,一名美国宇航员碰巧把一把工具掉进了轨道,从而引发了人们对于这样一个猛冲猛撞的物体可能破坏一颗昂贵的卫星、甚至威胁上面的生命的危险性的担忧。过了不久,中国炸毁了它的一颗卫星,从而立即倍增了因为难以搜寻而显得十分危险的围绕轨道旋转的废弃物的数量。

世界再次认识到了存在于我们天空的奇怪状况。天空是一个特殊并且没有得到恰当管制的领地。随着全球污染和技术的出现,改变这一状况变成了一个越来越紧迫的问题。

在大多数情况下,天空的规则与那些管制世界上海洋的规则相似。除开那些近陆地的海洋——那是受到与该国陆地边界同样方法管制的,其他的海洋是属于人类共有的。其结果是,天空通常在人们心目中通常只是一种交通的概念。航线和战斗机是在与地面相近的“管制”空域运作的,至于国境,则被认为你飞得越高,那么其概念就越薄弱。在此方面执行的脆弱的条约大多是因为很少有国家能在如果高的领域主张其权利。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
