La crise des missiles cubains a 50 ans

CAMBRIDGE – Ce mois-ci marque le 50ème anniversaire de la crise des missiles cubains – ces 13 jours d’octobre 1962 durant lesquels le monde a probablement frôlé une guerre nucléaire. Le président John F. Kennedy a officiellement mis en garde l’Union Soviétique de ne pas introduire de missiles offensifs à Cuba. Mais le dirigeant soviétique Nikita Khrouchtchev a décidé de franchir en secret la ligne jaune établie par Kennedy et de mettre les Américains devant le fait accompli. La crise a éclaté après qu’un avion de surveillance américain ait découvert les missiles.

Certains des conseillers de Kennedy ont préconisé une attaque aérienne pour détruire ces missiles. Kennedy a mobilisé les troupes, mais a aussi cherché à gagner du temps en déclarant le blocus maritime de Cuba. La crise s’est apaisée lorsque les bateaux soviétiques transportant des missiles supplémentaires ont fait volte-face, et Khrouchtchev a consenti à retirer les missiles déjà installés sur l’île. Ainsi que l’a exprimé le Secrétaire d’état de l’époque, Dean Rusk : « Nous étions face à face, et je crois que c’est l’autre qui a juste cligné des yeux. »

De prime abord, ce fut un déroulement rationnel et prévisible. Les Etats-Unis avaient un avantage de 17 contre 1 en matière d’armement nucléaire. Les Soviétiques étaient largement dominés en terme de puissance de feu.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
