Jim Webb needed to make a splash at Tuesday night's Democratic presidential debate, and his chance to do it arrived early. As the rest of the field sparred over the Iraq war and use of force in Libya and other countries, Webb tried to interject.

But when he finally got a chance to speak, Webb's answer was more of a lecture than a smackdown.
