Actually, the article is pretty vague on specifics, not really worth a read since it doesn't expand on it's only real premise, that the guy has something important to say about his trip to Iraq.
My take was, that he was a typical Berkeley liberal, naive to the point of dangerous, and somehow ignorant enough to think that he could make the world peaceful by playing his sophomoric songs.
Any musician worth his salt would pull a stunt like this for publicity; publicity intended to impress hot young chicks and getting them in the sack.
Pop music has and will always be a means of getting a BJ.
I think this is the Chronic's way of publicizing his "annual Peace-in" or whatever he calls it. It's being held this weekend.
