There was no implied consensus in what you quote. It wasn't even about approval or people's opinions of the UN. I think you read this statement as something like "everyone believes that the UN is mostly incapable" (which would be about popular opinion) rather than "the UN is mostly incapable" (which can be measured, in this case, by reduction of deaths after the UN gets involved (or lack thereof, if that's the case)).
