You're right, it helped immensely. (It was good for a chuckle.)
FYI, here's a link to the text of the resolution in question (Public Law 107-243). I hope you'll note the clause in which the War Powers Resolution from 1973 is mentioned and its requirements are stated as being fulfilled (I think it's section 3-c). And presumably you'll recall that the War Powers Resolution was based on the authority granted Congress by Article 1, Section 8.
Similarly, I see no corresponding clause in which Congress claims to have passed Public Law 107-243 by the authority vested in the US Congress by the UN.
So originally, "all you saw was UN crap", but now that I've passed along the actal text to you, you can see how you erred. If you want.
