I want to thank you, gentlemen, for appearing before us today. I appreciate your testimony.
I'm a bit concerned when I hear you talking at the end about the fact that we need to demand accountability. It's great that we're engaging with them, but then earlier you had said that we've not seen any demonstrable and concrete improvements in the human rights situation.
Is most of what they're doing a public relations exercise rather than something that's practically affecting the people of Iran?
