How President Obama Might Make a Decision on Iran

From David Maraniss's new biography of the president (via Michiko Kakutani's review today), a comment about Obama's decision-making process from his mentor in community-organizing:

"He was not unwilling to take risks," Mr. Kellman said, "but was just this strange combination of someone who would have to weigh everything to death, and then take a dramatic risk at the end. He was reluctant to do confrontation, to push the other side because it might blow up -- and it might."

As someone who takes the President seriously when he says he will stop Iran from going nuclear, I'm focusing on the "take a dramatic risk at the end" bit.
