Will the Iran-U.S. nuclear deal be good for the region?
The Iran-U.S. nuclear deal, if it goes through, will have far-reaching and ambiguous effects on the region. A well-executed deal could suspend Iran's nuclear weapons program, deescalate a decades-old cold war between U.S. and Iran, and provide relief to millions of Iranians struggling with a crippled economy. A deal could also allow the Iranian government to double down on its support for the Assad regime in Syria, which is currently dropping barrel-bombs on its citizens. The deal could strain ties between the U.S. and its longtime allies in the Persian Gulf like Saudi Arabia. A deal could have effects on the price of oil, as well as Russia's economy and its government's behavior.
While the sum of the effects will be incalculable, engaging with Iran does create more opportunities to effectively deal with the very pressing problems that exist in the region -- not to mention the ones that will inevitably come up. For now, it's impossible to say if the framework for the U.S.-Iran deal is good news or bad news, but I'd risk that as a guess for moving forward, it's as good as any.
