President Obama doesn't know much about history.

In his therapeutic 2009 Cairo speech, Obama outlined all sorts of Islamic intellectual and technological pedigrees, several of which were undeserved. He exaggerated Muslim contributions to printing and medicine, for example, and was flat-out wrong about the catalysts for the European Renaissance and Enlightenment.

He also believes history follows some predetermined course, as if things always get better on their own. Obama often praises those he pronounces to be on the "right side of history." He also chastises others for being on the "wrong side of history" -- as if evil is vanished and the good thrives on autopilot.

When in 2009 millions of Iranians took to the streets to protest the thuggish theocracy, they wanted immediate U.S. support. Instead, Obama belatedly offered them banalities suggesting that in the end, they would end up "on the right side of history." Iranian reformers may indeed end up there, but it will not be because of some righteous inanimate force of history, or the prognostications of Barack Obama.

Obama often parrots Martin Luther King Jr.'s phrase about the arc of the moral universe bending toward justice. But King used that metaphor as an incentive to act, not as reassurance that matters will follow an inevitably positive course.

Another of Obama's historical refrains is his frequent sermon about behavior that doesn't belong in the 21st century. At various times he has lectured that the barbarous aggression of Vladimir Putin or ISIS has no place in our century and will "ultimately fail" -- as if we are all now sophisticates of an age that has at last transcended retrograde brutality and savagery.

In Obama's hazy sense of the end of history, things always must get better in the manner that updated models of iPhones and iPads are glitzier than the last. In fact, history is morally cyclical. Even technological progress is ethically neutral. It is a way either to bring more good things to more people or to facilitate evil all that much more quickly and effectively.

In the viciously modern 20th century -- when more lives may have been lost to war than in all prior centuries combined -- some 6 million Jews were put to death through high technology in a way well beyond the savagery of Attila the Hun or Tamerlane. Beheading in the Islamic world is as common in the 21st century as it was in the eighth century -- and as it will probably be in the 22nd. The carnage of the Somme and Dresden trumped anything that the Greeks, Romans, Franks, Turks or Venetians could have imagined.

What explains Obama's confusion?
