 To resolve the debate, later in July 1965, McNamara visited South Vietnam on yet another "fact-finding mission" for President Johnson and met the new South Vietnamese Premier, Air Marshal Nguyễn Cao Kỳ who had just overthrown Khánh.Kỳ wore a flamboyant uniform which he had designed himself of a white jacket, black pants, red socks and black shoes which led McNamara to dub him as looking "like a saxophone player in a second-rate nightclub".McNamara was not impressed with Kỳ, reporting to Johnson that he saw little evidence that he was capable of winning the war, and the United States would have to send more troops to South Vietnam.
