I would like to take this opportunity to say a word about the American spirit in this time of trial.
In the most critical periods of our nation’s history, there have always been those fringes of our society who have sought to escape their own responsibility by finding a simple solution, an appealing slogan, or a convenient scapegoat.
Financial crises could be explained by the presence of too many immigrants or too few greenbacks.
War could be attributed to munitions makers or international bankers.
Peace conferences failed because we were duped by the British or tricked by the French or deceived by the Russians.
It was not the presence of Soviet troops in Eastern Europe that drove it to communism, it was the sell-out at Yalta. It was not a civil war that removed China from the free world, it was treason in high places. At times these fanatics have achieved a temporary success among those who lack the will or the vision to face unpleasant tasks or unsolved problems.
But in time the basic good sense and stability of the great American consensus has always prevailed.
