"This is a war specifically against Iraq, not a military action against terrorism in general. I think that distinction points to a legal requirement to declare war. It would be the first time since the founding of the UN, and in that sense would be peculiarly appropriate."
Actually they gave him power to go to war with any nation that harbor and aid terriorests. I think that would include Iraq, France, and Germany.
This is a political opportunity. Why would we avoid it?
