In the wake of the controversy over President Obama’s offensive labeling of anti-Semitic violence as “random,” it became clear that regardless of whether he chose his words carefully, he certainly chose his audience carefully. He was not challenged by his interviewer at Vox for his undeniably false characterization of the Paris attacks. And now, having given an interview to BuzzFeed’s Ben Smith, he has continued exposing his own ignorance in the hope that he would continue not to be called on it by his interviewers. He was in luck yet again.

BuzzFeed has posted the transcript of the interview, and when the subject turns to Russia, Obama said this:

You know, I don’t want to psychoanalyze Mr. Putin. I will say that he has a foot very much in the Soviet past. That’s how he came of age. He ran the KGB. Those were his formative experiences. So I think he looks at problems through this Cold War lens, and, as a consequence, I think he’s missed some opportunities for Russia to diversify its economy, to strengthen its relationship with its neighbors, to represent something different than the old Soviet-style aggression. You know, I continue to hold out the prospect of Russia taking a diplomatic offering from what they’ve done in Ukraine. I think, to their credit, they’ve been able to compartmentalize and continue to work with us on issues like Iran’s nuclear program.

As people pointed out immediately, Obama is wrong about Putin and the KGB. Ben Judah, a journalist who recently wrote a book on Putin’s Russia, responded: “The interesting and informative thing about Obama’s view on Putin is how uninsightful and uniformed it is.”

Putin ran the FSB–the successor agency to the KGB–and the difference matters. But what also matters is the emerging pattern for Obama’s view of the world: he has no idea what he’s talking about. The president, as Sam Cooke sang, don’t know much about history. And it’s evident in each major area of conflict the president seeks to solve and ends up only exacerbating.

It is not my intention to run down a list of all Obama’s flubs. Everybody makes mistakes, and any politician whose words are as scrutinized as the president’s is going to have their share of slip-ups. Yes, Obama is a clumsy public speaker; but that’s not the problem, nor is it worth spending much time on.

The problem is that Obama tends to make mistakes that stem from a worldview often at odds with reality. Russia is a good example. Does it matter that Obama doesn’t know the basics of Vladimir Putin’s biography and the transition of post-Soviet state security? Yes, it does, because Obama’s habit of misreading Putin has been at the center of his administration’s failed Russia policy. And it matters with regard not only to Russia but to his broader foreign policy because Obama has a habit of not listening to anyone not named Jarrett. Obama appointed among the most qualified American ambassadors ever to represent the U.S. abroad in sending Michael McFaul to Moscow. But with or without McFaul, Obama let his own naïveté guide him.

Obama has also run into some trouble with history in the Middle East, where history is both exceedingly important and practically weaponized. The legitimacy of the Jewish state is of particular relevance to the conflict. So Obama was criticized widely for undermining that legitimacy in his famous 2009 Cairo speech, puzzling even Israel’s strident leftists. The speech was harder to defend than either his remarks to BuzzFeed or Vox because such speeches are not off the cuff; they are carefully scrutinized by the administration. When Obama could say exactly what he meant to say, in other words, this is what he chose to say.

It wasn’t the only time Obama revealed his ignorance of the Middle East and especially Israeli history, of course. And that ignorance has had consequences. Obama has learned nothing from the history of the Israeli-Palestinian conflict, a fact which was reflected quite clearly in his disastrous mishandling of the negotiations and their bloody aftermath. He didn’t understand Palestinian intentions, Israeli political reality, or the lessons from when the U.S. has played a beneficial role in the conflict in the past. The president can simply move on, but Israelis and Palestinians have to pay the price for his learning curve.

And the Vox errors echo throughout the president’s mishandling of the other great security challenge: Islamic terrorism. Such terrorism has contributed a great deal to the undoing of many of the gains in Iraq and the international state system. Here, for example, is a map tweeted out last week by Ian Bremmer, which shows, in his words, “Statelessness overlapping with radical Islam.” We can certainly argue over the chicken-or-egg quality to such an overlap, but the threat radical Islamic violence poses to global order is fairly obvious.

Yet it’s not just the history of Islam and of anti-Semitism that the president gets wrong when trying to spin away the threat of Islamist terror. He also created a firestorm with his faux history of the Crusades in order to draw a false moral equivalence that only obscures the threat.

In other words, it’s a comprehensive historical ignorance. And on matters of great significance–the major world religions, the Middle East, Russia. And the president’s unwillingness to grasp the past certainly gives reason for concern with Iran as well–a country whose government has used the façade of negotiations to its own anti-American ends for long enough to see the pattern.

They’re not just minor gaffes or verbal blunders. They serve as a window into the mind of a president who acts as if a history of the world before yesterday could fit on a postcard. We talk a lot about the defects of the president’s ideology, but not about his ignorance. The two are related, but the latter is lately the one causing a disproportionate amount of damage.
