Ulmo, you are incorrect. The President has authority to undertake retaliation for the September 11th attacks from the Congress. Also as commander in chief he has authority to defend the US, and by implication retaliate against unprovoked attacks. He may also undertake other military actions when needed. We did this in the 1790 in the Quasi War with France, in the early 1800s versus the Barbary Pirates, the anti-slavery patrols off of Africa, the Boxer Rebellion expedition of 1900, etc.
