Roland Paris, soon to be a neighbor (I am moving his way), is a sharp guy, and has posted in various places some interesting stuff, including this look back at the NATO effort over Libya. I don't always agree with him, but that is because I tend to be a stubborn and agreement is boring.
Anyhow, a couple things to add to his analysis:
First, regarding his third asterisk: Russia learned from its mistake, just as the USSR learned not to boycott UN Security Council meetings when North Korea invaded South Korea in 1950. Russia is not going to let any resolution that authorizes force against any country for R2P kinds of stuff anymore. NATO/UK/France/US got their one shot. Lesson learned. Oh, and China learned the same lesson.
Second, Roland over-estimates the intra-NATO struggling towards the end of the campaign. Yes, countries wobbled, but once the conflict becomes defined as "we need to do this not so much for country x, but for the credibility/survival/future of NATO," there is enough rallying of support to continue and even escalate (US starts making ground campaign noises in June 1999). So, NATO permits much alliance discord but sallys onward anyway.
The funny thing on this second point is that Liberal IR types (especially institutionalists) tend to argue that institutions become not just the means but the ends of policy. NATO is a perfect example of this. So, does that make me a better Liberal than Roland? Certainly not, just a snarkier one.
