Because Japan and Germany were allies, and we declared war on Japan and Germany in turn declared war on us;

Because Hitler declared war on us and in such a case we certainly need not wait until he DOES fire a shot;

(Hussein did not declare war on us)

and because Hitler had been at war with our allies and was marching all over Europe for two years prior.

(Hussein had not attacked any of his neighbors or any of our allies since we liberated Kuwait.)

There is no rational comparison between our involvement in the European theater in WWII and our first strike in Iraq.
