"The vice president has been roundly judged delusional, pathologically dishonest or just plain nuts."

The vice president's on-camera crackup reflected his understandable fear that a White House cover-up was crumbling. He knew that sworn testimony in a Washington courtroom would reveal still more sordid details about how the administration lied to take the country into war in Iraq. He knew that those revelations could cripple the White House's current campaign to escalate that war and foment apocalyptic scenarios about Iran. Scariest of all, he knew that he might yet have to testify under oath himself.
