I think that Iran with a nuclear weapon is extremely destabilizing. I think it could precipitate a nuclear arms race in the region.

There is going to be a nuclear arms race in the Middle East if Iran gets a nuclear weapon. And you are going to see it in Egypt, in Turkey, in the Emirates. All of those people will want that.

If you go on with this nuclear arms race, all you are going to do is make the rubble bounce.

Our goal is simple: to stop Iran from obtaining a nuclear weapon.

If you're Iran's minister of defense, I think you'd try to develop at least one nuclear weapon to save yourself from what happened to Iraq.

If Iran becomes a nuclear weapon state it is the end of non-proliferation as we know it. If Iran gets a nuclear weapon you are likely to see Saudi, Egypt and other countries follow suit and we will bequeath to the next generation a nuclear arms race in the world's most unstable region.
