"Iran's nuclear ambitions are not in the world's interest," Bush said. "If Iran has a nuclear weapon, it will be incredibly destabilizing and obviously threatening a strong ally."
"If they continue to move forward with the program, there has to be a consequence," Bush said. "And a good place to start is working together to isolate the country. And my hope is, is that there are rational people inside the government that recognize isolation is not in their country's interest."
Bush said if the Iranians want to have a dialogue, "We have shown them a way forward," referring to the U.S.-European demand that Iran halt enrichment.
