Sanctions against Iran?

Deepti Choubey - the deputy director of the Nuclear Policy Program at the Carnegie Endowment

Today our guest is Deepti Choubey. The Western powers want the UN Security Council to approve a new sanctions resolution against Iran. On March 1 the Russian president said that Moscow could back these new sanctions against Iran, though there is still room for further diplomatic efforts. Are the sanctions the only instrument left to resolve the issue? I hope we'll get the answers today from the deputy director of the Nuclear Policy Program at the Carnegie Endowment.
