The single biggest threat that we face is a nuclear weapon or some weapon of mass destruction. What that means is that we have to be extraordinarily aggressive and vigilant in controlling nuclear proliferation.

We are learning more as we interrogate or have discussions with Iraqi scientists and people within the Iraqi structure, that perhaps he destroyed some, perhaps he dispersed some... And so we will find them.
