Durban and Kellogg-Briand

Last week, looking over various comments (including this) on COP 17, the following came to mind: 

I wonder sometimes if Durban and the COP process generally is a little like the negotiations that led up to the Kellogg-Briand pact outlawing war.  Lots of good intentions, but the real action was elsewhere.   This is not to say that trying to negotiate treaties on war and violence is totally pointless; they did, for example, lead to the Geneva conventions.
