The people of the United States have been profoundly
shocked by the unprovoked and ruthless aggression upon the people of
Yugoslavia. The Government and people of the United States are witnessing
with admiration the courageous self-defense of the Yugoslav people,
which constitutes one more shining example of their traditional bravery.
As I have assured Your Majesty's Government, the United
States will speedily furnish all material assistance possible in accordance
with its existing statutes.
I send Your Majesty my most earnest hopes for a successful
resistance to this criminal assault upon the independence and integrity
of your country.
