Months after chemical weapons were used in Syria and months after a UN investigation team was created, prepped and ready to go, two UN officials have come and gone to Syria on a two-day visit. The UN then issued a one-sentence press release which announces the culmination of the months of discussion on "the modalities" of any investigation. Here you have it: "The discussions were thorough and productive and led to an agreement on the way forward." No date. No details. No use.
