Shortly after joining the United States, China, the UK, France, and Germany in signing an agreement with Iran on a framework for a nuclear deal, the Russian government announced that it had lifted a ban on the export of S-300 missiles to Iran. Speaking to KCRW’s To The Point, Carnegie’s Andrew Weiss talked about the potential consequences for regional security and the reaction in Washington.

Weiss also discussed Russia’s rationale for lifting the ban, suggesting that economic woes spurred Moscow’s decision to send missiles to Tehran and that members of Russian President Vladimir Putin’s inner circle stand to benefit from the deal.
