Against who? It would have been easy to declare war on Al Qaeda after 9/11, but now there are so many splinter groups that such a declaration would be meaningless. And what would it achieve?
Well, let's let the President's advisors figure out the wording of the declaration. First, we have to have the will to seek a declaration. How would it help? There would be much more serious consequences politically and legally with regard to the type of over the top criticism that is coming from the left. Can you imagine Senator Kennedy spouting off if an official state of war existed? In addition, it would help the public to have a better grasp of the seriousness of the situation. With events as they are in Saudi Arabia, we may soon see as much as a 20% reduction in available oil. That will constitute an emergency that I believe needs to be backed up by a declaration of war.
It would take a small step in the direction of respecting the Constitution - - - after decades of "police actions" and "executive military actions" ratified by appropriations after the fact.
