Iran Analysis: Reading the Lack of Progress at This Week's Nuclear Talks
Why is Iran choosing to give a message this way --- through an unnamed source --- rather than criticising the West's proposals more directly via named officials speaking to State media?

If the West does not budge on its proposals, we are likely to see a stronger, official response from Iran at that stage.
