The some beneficiaries is a joke. You check your own sources - under Gaddafi, per capita income in the country rose to more than US$11,000 - the 5th highest in Africa. Universal free healthcare did exist and was not limited to "some beneficiaries" as you claim. Now, most Libyans suffer extreme poverty and deprivation. A nation that was utterly decimated - all thanks to NATO under the Obama administration.
The funny thing is that Gadaffi was willing to step down from power and hold elections under international observers. The U.S. rejected that. That would mean not having a war and hawks like Victoria Nuland wanted the Libyan government destroyed - not merely brought under democratic leadership. They were aware that if real elections were held and monitored with observers - Gadaffi would likely win and NATO legitimacy for the War would be lost.

In every country ruled by some dictator there are beneficiaries who will complain afterwards that the bloodshed was caused by some foreign intervention. They feed from his hands, receive generous giveaways while others suffer. Did you talk to those people to get your opinion?
