I did a Google search for "Bush use of nuclear weapons". This is the most authorative link I found:

Bush officials downplay story on nuke plans
WASHINGTON (CNN) -- Bush administration and military officials said Sunday the United States reserves the right to use nuclear weapons in the event it or its allies are attacked, but said that option does not represent a change in policy.

I didn't see any that advocated a first strike. All the links seem to be plans to use nukes in response to an attack on us or our allies.
