New York( CNN) The Obama administration's controversial decision to intervene in Libya against the late despot Moammar Gadhafi was correct, despite a “very challenging” aftermath, according to Samantha Power, the U.S. ambassador to the United nations organization.

“It seemed as though the added benefit of acting militarily — if we could obtain U.N. Security Council support — outstripped the costs, in the interests of … what we were ensure unfolding on the ground, ” Power told David Axelrod on “The Axe Files, ” a podcast produced by CNN and the University of Chicago Institute of Politics.

“I think we also had a sense — and this is something you never genuinely hear talked about today — that Humpty Dumpty was already broken. There had already been a revolution and a revolution where people had expressed their uprising and revulsion at Gadhafi's form of rule over so many decades, ” she told. “The idea that this was going to be set tidily back into the box if one simply stood back, I think, was extremely unlikely … It's not as if( Gadhafi) goes into Benghazi and hunts people down like rats and that's the end of this revolution. So some amount of instability is going to exist in this area now that it's been unleashed.”
