I thought is was clear -- Declare War.
Without a declaration, this war can go on as long as the the prez. wants, because there will never be a declared victory. Think about it -- living with armed guards all over the place. Americans being clasified as terrorists simply because they exercise the right to express their views. The possibilities are endless. The terrorists won!
This is a global reaction to an atrocity, not some local broken treaty skirmish.
only your mind.
