Most of the reportage on the Indo-US negotiations on the nuclear deal led from an optimistic statement of State Department spokesman Sean McCormack issued on Wednesday, a day after the talks concluded noting that “US is encouraged by the extensive progress that was made on the issues. We look forward to resolving the outstanding issues in the weeks ahead. In that regard Under Secretary Nicholas Burns will visit India in the second half of May to reach a final agreement.”
However, in McCormack's daily noon briefing on Tuesday, the nuance was decidedly neutral, if not a shade pessimistic. He said “Foreign Secretary [Shivshankar Menon] came here with some constructive ideas. …we are confident that the Indian side is ready to work in good faith to get an agreement, that we will get one done and that it's going to require some creativity and some compromise on both sides in order to get an agreement done if we're going to be able to move this as quickly as we would have hoped. We're at a point now where we’re going to see whether or not the agreement can be moved forward quickly or not.”
What changed between Tuesday afternoon and Wednesday? Probably the meeting with Secretary of State Condoleezza Rice who “stopped by” the afternoon session of the meeting on Tuesday.
