I want to talk about our common responsibilities in the face of a common danger. The events of recent weeks may have helped to illuminate that challenge for some; but the dimensions of its threat have loomed large on the horizon for many years. Whatever our hopes may be for the future - for reducing this threat or living with it - there is no escaping either the gravity or the totality of its challenge to our survival and to our security - a challenge that confronts us in unaccustomed ways in every sphere of human activity. This deadly challenge imposes upon our society two requirements of direct concern both to the press and to the President - two requirements that may seem almost contradictory in tone, but which must be reconciled and fulfilled if we are to meet this national peril. I refer, first, to the need for a far greater public information; and, second, to the need for far greater official secrecy.
