Donald Rumsfeld was a live guest for the hour on "Piers Morgan Tonight" and he discussed the Afghanistan, 9/11 and more. Piers Morgan asked him to compare invading Iraq with potentially invading Libya – would he advise invading Gadhafi's country? "No I wouldn't," said Rumsfeld. "I think it would not necessarily be a way to stop that."

Piers and Rumsfeld argued over the invasion of Iraq as well. "Would you have been very happy to go in regardless of the WMD issue?" asked Piers, to which Rumsfeld said "no." "I don't follow that argument," responded Piers. Said Rumsfeld: "It was a combination of things. It was the rejection fo the UN 17 times, it was his behavior on his own people, it was the weapons of mass destruction..."

On last night's "Piers Morgan Tonight", Piers Morgan interviewed the hosts of "The Talk" about the biggest issues facing women today, "The View" and more. But they also discussed one of the big stories of the day – Charlie Sheen. "Speaking as a parent, you only want the best for your child...and trying to put myself in any parents shoes who are facing problems like we're seeing with Charlie Sheen, it's heartbreaking," said Julie Chen. "I look at it from a mother," said Sharon Osbourne. "I know the damage that behavior does to a family."
