Cable to President Vargas on Brazil's Declaration of War.
I have been informed that the United States of Brazil has today recognized that a state of war exists between Brazil, on one hand, and Germany and Italy on the other hand.
On behalf of the Government and people of the United States I express to Your Excellency the profound emotion with which this courageous action has been received in this country. This solemn decision more firmly aligns the people of Brazil with the free peoples of the world in a relentless struggle against the lawless and predatory Axis powers. It adds power and strength, moral and material, to the armies of liberty. As brothers in arms, our soldiers and sailors will write a new page in the history of friendship, confidence, and cooperation which has marked since the earliest days of independence relations between your country and mine.
The action taken today by your Government has hastened the coming of the inevitable victory of freedom over oppression, of Christian religion over the forces of evil and darkness.
I send you my warmest personal regards and expressions of the fullest confidence in the success of our common cause.
