If we have isolated individuals able to inflict enormous harm, imagine what a single lunatic can do with a nuclear weapon. I think the whole base of civil society is at risk.

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

I think the Iranians are clearly determined to have a nuclear program. And we have to assume that with a nuclear program they have the capability and the will to create 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.

The nuclear weapon is obsolete. I want to get rid of them all.

The risk of just one terrorist with just one nuclear weapon is a risk we simply cannot afford to take.
