Are you trying to justify the attack of Libya, or discredit the invasion of Iraq? Either way, you are missing your goal.
Obama actually lied about what Qaddafi said. He did not threaten to destroy the city, he was telling the residents that he would root the rebels out of it. The man is crazy, but he was trying to encourage the city that he would not rest until he had rooter the enemy out.
Just womthing to think about.
Gaddhafi literally threatened to go house to house to root out and kill the rebellious people of the city in question.
Obama didn't re-write or parse what he said, Gaddhafi said it, period.
Now, I don't know about you, but it seems to me that if a proven terrorist leader makes a statement like that, I'm going to take him at his word.
Now, as to "justifying the attack on Libya", I don't feel that that's even necessary, until someone feels that it's necessary to justify Reagan's attack on Libya in the 80's.
Bush's invasion of Iraq, however, was based on a complete fabrication, and cost thousands of American lives, not to mention tens of thousands of Americans who are now maimed.
As far as I know, there have been no Americans killed in Libya. Unless you have some evidence to the contrary.
