At the top of these threats is Iran. Iran threatens the security of Israel and the entire world. Let me be clear: Under no circumstances can Iran be allowed to have nuclear weapons. For years, the US hasn't done enough to deal with what I have seen as a threat from Iran. As my country stayed on the sidelines, these problems got worse...We have muddled along for far too long.

First, America should be negotiating directly with Iran, which Bush won't do ... what happens if America were to militarily strike Iran? Well you take this unstable, radical leader, and you make him a hero--that's the first thing that'll happen. The Iranian people will rally around him. The second thing that will happen is they will retaliate. And they have certainly some potential for retaliating here in the United States through some of these terrorist organizations they're close to, but we've got over a hundred thousand people right next door. And most people believe that they have an infrastructure for retaliation inside Iraq. So, that's the second thing that'll happen. And the third thing is there are a lot of analysts who believe that an air strike or a missile strike is not enough to be successful. To be successful we'd actually have to have troops on the ground, and where in the world would they come from?...
So, I just want to get it very clear, you think that attacking Iran would be a bad idea?
I think would have very bad consequences.

Can we live with a nuclear Iran?
I'm not ready to cross that bridge yet. I think that we have lots of opportunities that we've...We're not negotiating with them directly, what I just proposed has not been done. We're not being smart about how we engage with them. But I'm not ready to cross that bridge yet.
