Here's another excerpt from Jeffrey Goldberg's essay on President Obama's foreign policy:
One afternoon in late January, as I was leaving the Oval Office, I mentioned to Obama a moment from an interview in 2012 when he told me that he would not allow Iran to gain possession of a nuclear weapon. “You said, ‘I’m the president of the United States, I don’t bluff.’ ”
He said, “I don’t.”
Shortly after that interview four years ago, Ehud Barak, who was then the defense minister of Israel, asked me whether I thought Obama’s no-bluff promise was itself a bluff. I answered that I found it difficult to imagine that the leader of the United States would bluff about something so consequential. But Barak’s question had stayed with me. So as I stood in the doorway with the president, I asked: “Was it a bluff?” I told him that few people now believe he actually would have attacked Iran to keep it from getting a nuclear weapon.
“That’s interesting,” he said, noncommittally.
I started to talk: “Do you—”
He interrupted. “I actually would have,” he said, meaning that he would have struck Iran’s nuclear facilities. “If I saw them break out.”
He added, “Now, the argument that can’t be resolved, because it’s entirely situational, was what constitutes them getting” the bomb. “This was the argument I was having with Bibi Netanyahu.” Netanyahu wanted Obama to prevent Iran from being capable of building a bomb, not merely from possessing a bomb.
“You were right to believe it,” the president said. And then he made his key point. “This was in the category of an American interest.”
But is he bluffing even now? We'll probably never know.
