Reply #23: If it were a unilateral US intervention, I would agree. As a UN-sanctioned humanitarian

[pampango]

intervention, I disagree. The UN has used its Responsibility to Protect to intervene in:

Darfur
Sudan
Burma
Zimbabwe
The Democratic Republic of Congo
Sri Lanka
Kenya
Guinea
Nigeria
Kyrgyzstan
Côte d’Ivoire

The others you mentioned (Rwanda, Kosovo and Cambodia ("killing fields")) occurred before R2P was adopted in 2005. Indeed it was the lack of UN action in those cases that spurred the adoption by the UN of R2P so that such humanitarian crises would not be ignored in the future.

Now if you're saying that the entire Security Council was duped or stupid, you may have a case.
