Like any news, especially pertaining to arms control, we should keep our fingers crossed and hope for a potential breakthrough. Assuming that talks go forward, and I think they will, I believe that the US and Iran should begin with areas of mutual gain. This should include nuclear safety vis-a-vis non-state actors. Both the US and Iran face numerous threats from terrorist. More so, they share a common enemy in al Qaeda and other Sunni groups. Al Qaeda attacked the US multiple times in the 1990s, which culminated in the 9/11 attacks. Iran was also attacked by al Qaeda in 1998, 2007 and 2009. This shared concern can form the foundation of a US-Iranian détente. There are many ways that both countries can work to reduce the risk of nuclear terrorism. The US should propose sharing nuclear detection technology with Iran. Air “sniffers” which can detect nuclear particles should be leased or given to Iranian port and airport authorities. Though focused on terrorists, these detectors would also increase trust. If genuinely shared, detectors would prove to the US that Iran is not using its transport infrastructure to share nuclear materials. While I doubt future negotiations will result in an Obama in Iran moment (or dare I say a future Hillary in Iran moment!), there are tangible solutions to the current impasse. Both sides have an opportunity to unclench their fist and grab the low hanging fruit.
