Le combat en ligne contre l'EI

WASHINGTON, DC – Même si les États-Unis et leurs alliés effectuent des bombardements aériens en Irak et en Syrie, leur cible, l'État islamique (EI), se prépare peut-être à riposter sur un autre front. En introduisant le conflit dans le cyberespace, l'EI pourrait bénéficier des nombreux avantages de la guerre asymétrique, à moins que les États-Unis ne s'organisent pour contrer les efforts du groupe.

Les barrières à l'entrée de la cyber-guerre sont remarquablement faciles à franchir, même pour les acteurs non étatiques. Même si l'EI ne dispose pas actuellement de la capacité à mener des cyber-attaques, il est peu probable qu'il lui soit difficile de recruter des adeptes disposant de l'expertise requise : dans le passé, d'autres organisations de terroristes et d'insurgés, notamment Al-Qaïda, ont procédé exactement selon ce schéma. Pour un prix alléchant, il y a forcément des cyber-mercenaires, des sympathisants et des freelances disponibles.

Les experts ont mis en garde contre le fait que l'EI puisse frapper des infrastructures non protégées ou des résidences privées. Des centaines de milliers de systèmes de contrôle industriels et commerciaux, y compris l'Internet des objets caractérisé par une croissance rapide, laissent une part toujours plus grande de la vie quotidienne sous la menace de perturbations potentielles.Un fait bien plus troublant est cet avertissement de la part de la Nuclear Threat Initiative, une association à un but non lucratif consacrée au renforcement de la sécurité mondiale, qui prétend que de nombreuses installations nucléaires civiles et militaires ne seraient pas suffisamment protégées contre les cyber-attaques.

    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.

    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.
