Not much of a question, is it? The sovereign is by definition that which can't be disciplined. The only hope I can see is in very widespread withdrawal of support for the regime. That certainly won't happen so long as people want the sovereign to win wars for us, or provide all sorts of other goodies, or so long as people say, "I don't understand why we attacked Iraq, but I'm sure the President knows things he can't tell us"--or so long, in general, as we cling to the comforting myth of the sovereign as benevolent protector.
