" Harry S. Truman, said Krock, might seem to many a controversial figure. But to those who had the chance to talk with him intimately, his faith in the future had a “luminous” quality. He sits in the center of the troubled and frightened world. . . . But the penumbra of doubt and fear in which the American nation pursues its great and most perilous adventure . . . stops short of him. Visitors find him undaunted and sure that, whether in his time or thereafter, a way will be discovered to preserve the world from the destruction which to many seems unavoidable. . . . "

― David McCullough , Truman
