The weapons of destruction have become so powerful and so terrible that we can't even think of another all-out war.
As President, I feel it my duty to protect the men who are engaged in this crucial work from such attacks.
I believe that God intended for this Nation to lead the way to peace for all men, and that we are going ahead to lead it...
We have brought this country the greatest prosperity and the highest standard of living in history.
