Three powerful women are leading the latest round of negotiations with Iran over its nuclear activities. Cathy Ashton, the European Union's policy chief and a lead negotiator, has taken great care to set the right tone for the discussions by reaching out to Iranian allies around the world. Ashton's deputy, Helga Schmid, is Germany's political director and will meet with Iran's second-ranking nuclear negotiator. Undersecretary of State for Political Affairs Wendy Sherman is leading the U.S. delegation for the talks. Sherman worked on the Clinton administration's negotiations with North Korea.
