For the Geneva II conference on Syria to have the best chance of enacting a cease-fire and beginning a transition, Iran needs to be there.
US Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov met on May 15 in Sweden for further consultations toward convening the conference, the purpose of which, according to Kerry, is “to implement a peaceful resolution based on Geneva I, which recognizes the need for a transition government with full executive authority by mutual consent.”
