We may need, however, to have a bit of a mobilization similar to, though not on the scale of, World War II.
Also, we should consider that the Chinese could take advantage of the fact that our armed forces will be largely tied up thousands of miles from Taiwan. If the North Koreans coordinate with them, we'll have a formidable problem. This speaks to me of the need to mobilize somewhat, just as a precaution. This is why I believe that we need a declaration of war - the entire world should know that we are serious, and Bush will need the authority and money to do some very serious things.
A declaration of war is critically important.
