The NGO was left in the embarrassing position of expressing their disappointment that they wouldn't be able to achieve their goals at the current time. Unfortunately they set it up for review again--can't remember for sure--couple of years or 5 years from then. I guess they're hoping we have another treasonous administration by then which would go along with them.
But I can't get excited about something that can be taken up and in five years and passed. It's not over for this treaty by a long shot and to me that isn't good news.
The people with the real power, didn't sign this letter, the Senate that passes treaties they claim not to have read on voice votes, in hidden rooms away from the public eye, so to me it's smoke and mirrors.
