My balls are still big enough to walk through a conflict zone unarmed, as the father of six children, etc. I admit to having had some of them bouncing against my jaw; it felt good. I have never tried marijuana or cocaine. What's your excuse?
Back on topic......it appears the president did not have authority to wage war, except through the UN. It's also obvious that Congress did not DECLARE war in accordance with the Constitution; not since 1942. And it ain't no semantical exercise; Congress is quite fluent in legislative vocabulary. The words are "The USA hereby declares war on...."
And if you think the UN has done nothing good in 60 years, you're more ignorant than you first appeared to be. Do you think the Korean war was worth doing? UN. The liberation of Kuwait in gulf war one? UN. Not counting the mercenaries who rape women, the UN Peacekeeping Forces earned the Nobel Peace Prize, as did UNESCO and some other UN agencies. Bringing up the UN scandal about the Food for Oil program is just a red herring.
But I'm often wrong.
