A long life in journalism convinced me many Presidents ago that there should be a large air space between a journalist and the head of a state. I would have carved on the portals of the National Press Club, 'Put not your trust in princes.' Only the very rarest of princes can endure even a little criticism, and few of them can put up with even a pause in the adulation.
