The following is the letter written from President Eisenhower to South Vietnamese Ngo Dinh Diem in which he promises to help South Vietnam against the Communist North.
October 23, 1954
Dear Mr. President,
I have been following with great interest the course of developments in Vietnam, particularly since the conclusion of the conference at Geneva. 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.
We have been exploring ways and means to permit our aid to Vietnam to be more effective and to make a greater contribution to the welfare and stability of the Government of Vietnam. I am, accordingly, instructing the American Ambassador to Vietnam [Donald R. Heath] to examine with you in your capacity as Chief of Government, how an intelligent program of American aid given directly to your Government can serve to assist Vietnam in its present hour of trial, provided that your Government is prepared to give assurances as to the standards of performance it would be able to maintain in the event such aid were supplied.
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. The Government of the United States expects that this aid will be met by performance on the part of the Government of Vietnam in undertaking needed reforms. It hopes that such aid, combined with your own continuing efforts, will contribute effectively toward an independent Vietnam endowed with a strong Government. 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.
