"I like her," Biden said of his former Vice-Presidential foe, who has been the subject of criticism lately scribbling speech notes on her hand while a guest at a Tea Party Convention.
Biden said he thinks "she's an engaging person, a great personality." But he said some of her comments are "far out there."
King hosted First Lady Michelle Obama on Tuesday night, who had little to say when asked about Palin, saying she didn't know her.
Biden told King he thinks a massive, 9/11-type attack in the United States is "unlikely, in my view."
"If you see what's happening, particularly with al Qaeda and the Arabian Peninsula," he said, "they have decided to move in the direction of much more small but devastatingly frightening attacks," Biden said.
Biden was optimistic about Iraq, saying troop withdrawals and a stable Iraqi government could be one of the greatest achievements of the Obama administration.
However, the VP expressed concern over Pakistan -- making clear the administration's view that it poses more of a threat than Iraq, Iran, and Afghanistan. Biden was a long-time member of the U.S Senate Committee on Foreign Relations, chairing the committee from 2001 to 2003. He's also made frequent trips to Islamabad.
"It's a big country," Biden said of Pakistan. "It has nuclear weapons that are able to be deployed. It has a real significant minority of radicalized population. It is not a completely functional democracy in the sense we think about it. And so ...
that's my greatest concern."
