The pitiful plight of oppressed people yearning to be free of the tyrant. Unable to accomplish the goal with their own heft (quite common in the Middle East), these potential allies, facing an existential threat from Qaddafi, pled with the US and NATO to help their cause for freedom and democracy. Democrats, one and all, they truly were.
They clamored for justice.
US politicians and the ever vigilant US media cranked up demand for Obama to do something. Obama, never quite capable of resisting the political winds caved to the call.
NATO, (read US: France and the UK) air power and US mercenaries rose to the occasion to get involved in something that they did not understand to support our natural and longtime allies, the Mujaheddin, Muslim Brotherhood, AQ, whatever.
How is that working out exactly now that the calls for US arms and money are clamoring across the lands of all those loving prophets and religions of peace?
