Judy Woodruff Lets Herman Cain Off the Hook

Andrew Sullivan points to this jaw-dropping exchange on PBS two days ago:

JUDY WOODRUFF: Do you view China as a potential military threat to the United States?

HERMAN CAIN: I do view China as a potential military threat to the United States....They've indicated that they're trying to develop nuclear capability and they want to develop more aircraft carriers like we have. So yes, we have to consider them a military threat.

I know, I know, who cares? Herman Cain is a clown. But that's not why I'm posting this. What I want to know is this: How on earth can a presidential candidate sit down for an interview with Judy Woodruff, spout a howler about China "trying to develop" nuclear weapons, and not get a followup question to suss out whether he has any idea that China has had nuclear capability for nearly half a century? Did Woodruff really not consider that worth drilling into a little bit?
