Retomar a Segurança Nuclear

VIENA – Nestes dias de angústia económica, doenças potencialmente pandémicas, e agitação civil generalizada, poderá parecer surpreendente que tantas pessoas à volta do mundo ainda encarem o conflito nuclear como a maior ameaça enfrentada pela humanidade.

Os acordos globais como o Tratado de Não-Proliferação Nuclear (TNP), juntamente com o sentimento geral de boa vontade imediatamente posterior à Guerra Fria, poderão ter criado a ideia de que uma arma desse tipo nunca seria usada em combate. Mas existe uma noção crescente de que poderemos não estar ainda completamente descansados.

With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving.
