When I was at the CIA I asked my civilian advisory board to tackle some tough questions. Among the toughest: In a political culture that every day demands more transparency and more public accountability from every aspect of national life, could American intelligence continue to survive and succeed? That jury is still out.

Despite a campaign that was based on a very powerful promise of transparency, President Obama, and again in my view quite correctly, has used the state secrets argument in a variety of courts, as much as President Bush.

For all of its well-deserved reputation for pragmatism, American popular culture frequently nurtures or at least tolerates preposterous views and theories. Witness the 9/11 'truthers' who, lacking any evidence whatsoever, claim that 9/11 was a Bush administration plot.
