In a May 10,1982 speech to Chatham House (the Royallnsti­ tute for International Affairs), Sir Henry Kissinger bragged that he had been a British agent in the Nixon and Ford adminis­ trations,serving as Presidential adviser for national security and secretary of state. (Today, Kissinger is Honorary Knight Commander of the Order of St. Michael and St. George, a rank normally given to top British diplomats.) In his speech, Kissinger stated that he had pursued British policy in these positions irrespective of the sovereign concerns of the United States, which he ostensibly was serving.
Excerpts from that speech, entitled “Reflections on a Partnership: British and American Attitudes to Postwar Foreign Policy,” include the following statements:

“The British were so matter-of-factly helpful that they became a participant in internal American deliberations, to a degree probably never practiced between sovereign nations. In my period in office, the British played a seminal part in certain American bilateral negotiations with the Soviet Union-indeed, they helped draft the key document. In my White House incarnation then, I kept the British Foreign Of­
fice better informed and more closely engaged than I did the American State Department…. It was symptomatic [empha­ sis added]. . . .
“In my negotiations over Rhodesia I worked from a Brit­ ish draft with British spelling even when I did not fully grasp the distinction between a working paper and a Cabinet-ap­ proved document. The practice of collaboration thrives to our day, with occasional ups and downs but even in the recent Falkland crisis, an inevitable return to the main theme of the relationship.”

Much of Kissinger’s speech, apart from these admissions of British agentry, was an attack on President Franklin Delano Roosevelt for challenging British Prime Minister Sir Winston Churchill’s adherence to empire.
