The Russians and the Chinese have been absolutely clear they don't want to see Iran with a nuclear weapon.

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

The nuclear weapon is obsolete.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

Iran can never get a nuclear weapon, and it never will as long as I have anything to say about it.

Iran has the technology to produce the highly enriched uranium, which is not automatically meaning nuclear weapon.

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