We Americans of today, together with our allies, are passing through a period of supreme test. It is a test of our courage—of our resolve—of our wisdom—our essential democracy. If we meet that test—successfully and honorably—we shall perform a service of historic importance which men and women and children will honor throughout all time. As I stand here today, having taken the solemn oath of office in the presence of my fellow countrymen—in the presence of our God— I know that it is America's purpose that we shall not fail.
