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.

It's a question of confidence and time.

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.

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

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.

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.
