Unfortunately there are few options for dealing with Iran's nuclear ambitions. I'm not a nuclear expert, so I must rely on those who are to ensure the best safeguards are in place. If congress rejects the deal it's almost a certainty that the international sanctions will fall apart. Sanctions from the U.S. alone will have no teeth making them virtually useless. We already tried going it alone with Cuba for over 50 years and we can see now how successful that was. I believe the negotiators made the best deal possible with real penalties in place for cheating. War with Iran seems to be the only other option with the U.S. once again paying with our blood and treasure. I don't think we can go through that again so soon.
