Former Iranian Ambassador: Trump’s Re-imposed Sanctions Against Iran Are an Act of Warfare

Tensions are escalating between the U.S. and Iran after the Trump administration re-imposed economic sanctions against Iran last week. This news followed Trump's decision to withdraw from the Iran nuclear deal. Trump has threatened other countries seeking to trade with Iran, tweeting, "Anyone doing business with Iran will NOT be doing business with the United States." Iranian President Hassan Rouhani condemned the sanctions as "psychological warfare," saying last week he would not begin negotiations until the sanctions are withdrawn. We speak with Ambassador Seyed Hossein Mousavian, Middle East security and nuclear policy specialist at Princeton University's Woodrow Wilson School of Public and International Affairs. He served as spokesperson for Iran in its nuclear negotiations with the European Union from 2003 to 2005.
