Lyndon Johnson actually said...

"In our hands have been placed the fortunes of peace and the hope of millions; it is my fervent hope that we are good stewards of that trust."

"We shall maintain in Vietnam American personnel and material as needed to assist you in achieving victory."

"I wish to congratulate you particularly on your work for the unity of all your people, including the Hoa Hao and Cao Dai, against the Viet Cong."

"As the forces of your government become increasingly capable of dealing with this aggression, American military personnel in South Vietnam can be progressively withdrawn."
