In an ongoing collaboration between Chatham House and the McDonald Centre, top scholars and other experts investigated the ethics of humanitarian intervention in a one-day colloquium in February 2011 entitled ‘After Libya: The Ethics of Military Intervention Revisited.’
Because the event was held under the Chatham House Rule, the full list of participants is confidential, but one of the observers posted this account(link is external) of the day. Much of the discussion concerned a newly-emerging, but also controversial, norm in international relations called ‘Responsibility to Protect’ (usually abbreviated R2P). This concept was compared to other approaches to military intervention, such as just war and human rights, especially in light of the recent conflict in Libya.
