Letter from U.S. President Eisenhower to Ngo Dinh Diem (1954).
"The implications of the agreement concerning Vietnam have caused
grave concern regarding the future of the country temporarily divided by an artificial military grouping, weakened by a long and exhausting war, and faced with enemies without
and by their subversive collaborators within. Your recent requests for aid to assist in
the formidable project of the movement of several hundred thousand loyal Vietnamese citizens away from areas which are passing under a de facto rule and political ideology which they abhor, are being fulfilled. I am glad that the United States is able to assist in this humanitarian effort...

The purpose of this offer is to assist the Government of Vietnam in developing and maintaining a strong, viable state, capable of resisting attempted subversion or
aggression through military means... Such a Government would, I hope, be so responsive to the nationalist aspirations of its people, so enlightened in purpose and
effective in performance, that it will be respected at home and abroad and discourage any who might wish to impose a foreign ideology on your free people."
