I think the way things are arranged in Mali is fairly sophisticated, with the French providing essentially the higher and direct CT operations, and the UN having a wider role. Even then, even in that context, the UN has to have the kinds of troop contributors that are capable of responding to and confronting attacks from AQIM and others.
Almost all operations since the mid-nineties have operated under chapter VII. That's a standard at this stage. The issue is, what's the character and the quality of the troop contributors? If you have an operation that has the option of responding under chapter VII but has low-capability troop contributors, you will end up with a real challenge between the purpose of why it's there and the authority it has, on the one hand, and its actual capabilities on the other.
Mali, Lebanon, Congo, the three places I mentioned, are where you've seen troop contributors come in that have a stronger capability and a willingness to be on the tougher edge of the peacekeeping spectrum. That has allowed the UN to implement its mandates in a more effective way in those contexts.
