My guess, although not necessarily being very informed, is that concerns for various interests will often be part of our political reality. Regardless of that, UNSCR 1973 is alive and being enforced.
I respect and share some concerns for some of the potential consequences of this action (bearing e.g. the Balkans in mind), but nonetheless I like to think that we're doing something right. I figure that the UN should have its reasons for the resolution and that some real moral considerations have been put into it.
I also have some thoughts and questions regarding responses to events in countries such as Sudan, Yemen, Syria etc. I can only guess that many considerations enter into this. We live in a complex and somewhat unfair world filled with unknowns, dilemmas, hard decisions etc. We can only do our best. Doing something might beat doing nothing. An inch is a mile, if you like.
Cheers
