"how do you explain Mrs Clintons disgraceful and misplaced triumphalism after the murder of Gaddafi?."

I don't... because she didn't.

I saw the news conferences. YOU have taken an 'announcement' and blown it up to suit YOUR ideas.

At the time, almost everyone saw the demise of Gaddafi as justice for his years of cruelty. You can't blame her for Libyans wanting him and his sons gone.
