Just How Vulnerable is Iran to Sanctions?

 Aaron Arnold, Associate at the Belfer Center for Science and International Affairs, writes in The National Interest that contrary to what some have argued, the more Iran is connected the to global economy, the more vulnerable it is to the snapback sanctions measures built into the Iranian nuclear deal. He argues that as Iran becomes more connected to the global economy, the American dominance of financial markets and the importance of the dollar as a global currency will mean that in the event of snapback, companies will be deterred from action in Iran. As a result, the more Iran reconnects its economy to the world, the more vulnerable it will be to snapback measures.
