re: Can we stop Iran from building nukes?

Iran like them or not is a stable country. Amending our foreign policy and working with them is in our long term best interest. Our old puppet the Shah and his regime will not be making a comeback much like Batista and his lot in Cuba.

The region needs to police itself along with Europe/China who have a significant interest as their direct shipments of oil flow from the areas.

Or, the region should pay a significant sur tax for our policing the waters which could be enforced by the world bank of which we control presently.
