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. …

If Obama believes that evil should be absent in the 21st century, or that the arc of the moral universe must always bend toward justice, or that being on the wrong side of history has consequences, then he may think inanimate forces can take care of things as we need merely watch.

In truth, history is messier. Unfortunately, only force will stop seventh-century monsters like ISIS from killing thousands more innocents. …

There is little evidence that human nature has changed over the centuries, despite massive government efforts to make us think and act nicer. What drives Putin, Boko Haram or ISIS are the same age-old passions, fears and sense of honor that over the centuries also moved Genghis Khan, the Sudanese Mahdists and the Barbary pirates.

Obama’s naive belief in predetermined history – especially when his facts are often wrong – is a poor substitute for concrete moral action.
