Major George Fielding Eliot, in the New York Herald Tribune, 4/14/45, in an article titled as this post is:

Lincoln gave his life that the Union might be preserved; he died before he knew that, from the wreck of war, a stronger and more enduring Union would arise. Franklin Roosevelt gave his life that a greater Union—a Union of all peace-loving peoples to achieve peace and guard the hard-won heritage of freedom—might rise from the desolation of a more terrible war than Lincoln ever imagined. He, too, died before he saw the fulfillment of his vision. To us who remain behind, he left the heritage and the responsibility of that vision, that bright hope from which his purpose never turned aside.
