'Iraqi Veterans Against War' has their own website and leaders at http://www.ivaw.net
I am aware of this and they correspond with VVAW and VVAW&AI who still exis and are quite active. The black guy you see heading up the demonstrations in Europe is a guy named Darnell Summers. He attempts to be active with the troops but they just laugh at him. He spent his Vietnam tour in the stockade at Long Binh Jail.
Drop them all a line and give them a piece of your mind. It makes a difference when you do that. THEY DO NOT LIKE IT.
