This photo was taken in June 1969, about the time that then-Captain Robinson started the secret "Duck Hook" planning for the National Security Council. Prior to beginning an assignment with the JCS Chairman's Staff Group in early 1969, during 1964-1968, Robinson had served four years as executive assistant and aide to the Commander-in-Chief Pacific (CINCPAC), where he was at a nerve center of Vietnam War military operations. During 1969-1972, Robinson also served as the NSC liaison to the JCS. Besides playing a key role on the NSC staff, beginning in 1970 Robinson initiated the JCS spying operation against Kissinger designed to keep JCS Chairman Moorer apprised of White House policy decisions affecting the military. Promoted to the rank of rear admiral in 1970, Robinson was commanding a flotilla in the Gulf of Tonkin when he was killed in a helicopter crash in May 1972. This occurred during the Linebacker I operations against North Vietnam which Robinson's earlier Duck Hook plans had presaged.
