On September 11 2001, America felt its vulnerability even to threats that gather on the other side of the Earth. We resolved then, and we are resolved today, to confront every threat from any source that could bring sudden terror and suffering to America.
George W. BushThis is a world that is much more uncertain than the past. In the past we were certain, we were certain it was us versus the Russians in the past. We were certain, and therefore we had huge nuclear arsenals aimed at each other to keep the peace. That's what we were certain of... You see, even though it's an uncertain world, we're certain of some things. We're certain that even though the "evil empire" may have passed, evil still remains.
