Late this week, President Obama nominated CIA Director Leon Panetta to replace retiring Defense Secretary Robert Gates. He also nominated Gen. David Petraeus to succeed Panetta at the CIA. What kind of marks does he give Panetta? How has the CIA changed under his watch? Is that change for the better? What does he expect – and fear – from Petraeus? We ask Herb Meyer, former special assistant to then-CIA Director Bill Casey and former vice-chairman of the National Intelligence Council. Meyer also offers some personal advice to Petraeus as he heads to Langley.
