When information which properly belongs to the public is systematically withheld by those in power, the people soon become ignorant of their own affairs, distrustful of those who manage them, and -- eventually -- incapable of determining their own destinies.
The destiny of our land, the air we breathe, the water we drink is not in the mystical hands of an uncontrollable agent, it is in our hands. A future which brings the balancing of our resources-preserving quality with quantity - is a future limited only by the boundaries of our will to get the job done.
I don't think that a leader can control, to any great extent, his destiny. Very seldom can he step in and change the situation if the forces of history are running in another direction.
