I beg to differ on the Spanish diversion; history says otherwise. But forget history--look at a map. France is in the way; Spain would have been a plan B route. France denied flyover rights because they wanted to review the mission. Right or wrong, the US military does not allow any other power to review its missions.
The US didn't take off from Italy, because there is only one USAF base in Italy, Aviano. It holds fighter jets, not bombers. The bombers are in England.
As to the UN resolution, you are correct. But they don't have a stellar track record of fully intelligent decisions.
The US bombing mission in Libya was a failure. Its purpose was to disable the state supported terrorism coming from Libya. The mission failed, and the US didn't pursue it further in such a form directly. Nobody knows this better than the people of Lockerbie, Scotland--additional victims of state sponsored terrorism two short years later.
Some years after that, before his past caught up with him, Qadaffi's Libya paid enormous financial reparations for its part in state-sponsored terrorism. I wonder what the UN had to say about that?
As to the diversions of topic, the cartoon was posted as a long-ago response to one interpretation of the French exception; that itself being one example of the massive complexities of understanding the EU. If you'd like to add 'the Spanish exception" and more, that just validates the complexity suggested. My Austrian friend simplified it for me once. He said that the EU has givers (such as Germany, Austria) and takers (such as Greece) and that's one big root of discontent that will not go away soon. The original video made it clear there's no understanding it, for not only is it massively complex, it's changing all the time!
