On your question concerning adaptation, I think the UN is a more adaptive organization than we often recognize. Especially on the issue of intelligence, which five years ago was really a taboo subject, we've seen huge progress. A wide range of states are now strongly supporting UN intelligence gathering, so change is possible.
I think it is worth recognizing that UN forces are still in very, very difficult environments. Even a NATO force would struggle in a situation such as Darfur or South Sudan. The UN is still trying to manage those operational environments with fewer capabilities. So it is adapting, but it is also dealing with very daunting mission settings.
