What [Barack Obama] and I did was to say clearly what we're doing, all the bluster, all of the sanctions, that are just imposed by the American government haven't had much impact.Let's see if we can put together an international coalition to really cripple Iran, and then maybe we can begin a negotiation, and that's what I did. It was difficult. We had to get China and Russia on board, and not just get them on board by signing a piece of paper.
