G20 puzzlement
I understand the motivation of the protesters. Marching and singing help to maintain the morale and the "emotional investment" of the participants; and the publicity (especially the bloody face pix!) increases fundraising and relative prestige of the leaders. Standard stuff, well known to military leaders from Sun Tzu to Schwartzkopf, and well known to ideological leaders from Jesus to Jessajackson.
But I don't understand why the presidents and prime ministers are there. Surely all of these men have access to telephones and computers. They can talk any time they want, without the inconvenience of a closed compound surrounded by protesters. Perhaps the smaller nations gain some prestige, but the big boys don't gain anything.
