Obviously, we have a very difficult problem ahead in dealing with Iran, something that I think the Bush administration put on the back burner for too long, outsourced to the French, the British and the Germans, instead of, you know, going forward and seeing if there were any ways that we could rein in this regime and certainly prevent it from obtaining nuclear weapons.

And that's going to be my focus as a senator and as president.

The sanctions are aimed at getting Iran to suspend its enrichment of uranium. The international efforts to rein in Iran’s nuclear ambitions have been complicated by America’s conflict with Iran in Iraq, which Russia and some European countries argue should take a back seat to the nuclear issue.
