It depends very much on the particular country and the case. South Sudan has been a relatively successful case where you've been able to get quite significant action through the UN Security Council. Other conflict situations like Yemen are much more difficult because there is a greater degree of polarization, where you have the United States, France, the U.K. maybe largely agreeing, and Russia and China often not agreeing.
That is a real reflection of some of the challenges in the multilateral system at the moment, which requires different approaches to diplomacy.
