Pugnacity was on display Sunday as former VP Cheney and current VP Biden argued over the Obama administration's handling of national security matters. It's what vice presidents do.

That's an easy one. That's the role of vice presidents – both current and former. It's expected. Pugnacity can be an asset for an administration's No. 2.
To start from the beginning, Mr. Cheney, the VP under George W. Bush, and Mr. Biden, current occupant of the VP mansion (it's on the Massachusetts Avenue grounds of the Naval Observatory), both appeared on Sunday morning news shows.
National security was the main area of contention. The Iraq war was "the right thing to do," said Cheney during an appearance on ABC's "This Week." "We got rid of one of the worst dictators of the 20th century."
