[David Dilks, ed., ''The Diaries of Sir Alexander Cadogan, 1938–1945,'' New York: G. P. Putnam's Sons, 1972, 8.] Eden returned the admiration, writing that Cadogan "carried out his thankless task with a rare blend of intelligence, sensibility, and patience."

[David Dilks, ed., ''The Diaries of Sir Alexander Cadogan, 1938–1945,'' New York: G. P. Putnam's Sons, 1972, 13.] However, this suggestion was not taken up by
Sir Robert Vansittart or Eden. It was felt that modifying the Treaty would only increase Germany's ambitions, a policy of appeasement which only encouraged the Nazi government to ask for more. despite the Cadogan disagreed and wrote in his diary: "I believe that, so long as she is allowed to nurse her resentment to her bosom, her claims increase with her armaments." He wanted to engage Germany in an effort to get German grievances set down on paper and was not as troubled by his colleagues about the possibility of German domination of Central Europe. Cadogan grew impatient with the lack of strategic direction in the Foreign Office. He complained, "It can't be said that our 'policy' so far has been successful. In fact we haven't ''got'' a policy; we merely wait to see what will happen to us next".
Permanent Under-Secretary
In 1938, Cadogan replaced
Robert Vansittart as
Permanent Under-Secretary at the Foreign Office. He considered his predecessor's style to be emotional and disordered compared to his own terse and efficient manner. There were, however, no significant divergences in policy although Vansittart's detestation of the dictators was more publicly known. Cadogan served in this capacity from 1938 to 1946 and represented Britain at the

The blood of Russians cries as loud to heaven as that of Poles. But it's very nasty. How can Poles ever live amicably alongside Russians, and how can we discuss with Russians execution of
German 'war criminals', when we have condoned this?" He was also involved in discussions about the composition of

. Both agreements entailed serious injury to the rights of states which could not defend themselves against large and predatory neighbours; both reflected the military and geographical facts; neither was a matter for pride or for fierce self-reproach, since it hardly lay in British power at the material time to do other; both looked better on signature than in the hard after-light." Cadogan wrote in his diary in January 1944: "They
he Soviet diplomatsare the most stinking creepy set of Jews I've ever come across." At the same time, he defended the Yalta Conference as relatively successful, writing “We have got an agreement on Poland which may heal differences, for some time at least, and assure some degree of independence for the Poles.”

. He served in this capacity from 1946 to 1950. During his time at the UN, as David Dilks points out, "British diplomacy had to be conducted from a precarious position of over-commitment and economic instability." Cadogan expressed great frustration with the inflexibility of his Soviet counterparts, who were forbidden from mixing with other delegations or informal exchanges of views. At one point, he asked himself, "How can ten men discuss with a ventriloquist's doll?" He saw many parallels between Soviet actions at the
beginning of the Cold War and those of the Germans on the
eve of the Second World War. He remarked to Winston Churchill, "What forces itself on one's attention is the degree to which everything favours the evildoer, if he is blatant enough. Any honest Government fights (in peacetime) with two hands tied behind its back. The brilliant blatancy of the Russians is something that we can admire but cannot emulate. It gives them a great advantage." Although he was never celebrated as a public figure, Cadogan enjoyed great prestige within diplomatic circles. He was widely respected for his ability, character and experience. He and his wife cultivated a large and varied number of friends by entertaining at their
