Hmm lets see:

Getting involved with a regime change in a Islamic country but having other Islamic countries urging the West to do it: check
Using UN SC this time: check
This time no fantastic tales of why to do it and most can see why it needs to be done ASAP: check
An apparent political opposition within the country, although poorly armed: check

I'd say some lessons have been learned.

I have no idea if it will be enough but I admit I'm a sucker for humanitarian bombing.
