When you look at all instruments of statecraft and how that's pulled together, I think the ambassadors are uniquely poised.

It's a question of confidence and time. I must stress though that in terms of intelligence cooperation, in terms of operational impact on the enemy, Libya is a good partner.

As catastrophic as a nuclear attack would be, it would be self-contained.

It is now well known that the terrorist cell that conducted the 9/11 attacks did much of its planning from a base in Europe.

We have no intelligence or evidence that indicates that he (Bin Laden) is dead or incapacitated, so our working assumption is that he is still alive.

But despite this shared perception of the threat, there is disagreement over the most effective means to counter the threat. Some European countries continue to argue that terrorism is merely -- or mainly -- a criminal problem.

However, Libya has made enormous progress in the last couple of years and we are hopeful that at some point we can address that question.
